UC Davis Health is scheduling COVID-19 vaccines

Get the latest on how to schedule your COVID-19 vaccine, boosters and third doses, and more.

UC Davis Health is committed to providing you with the most up-to-date information on COVID-19, including the latest on testing, how COVID-19 is spread, and COVID-19 vaccines. Learn more about the virus so you can better protect yourself and your family:

The novel coronavirus (COVID-19), which originated in Wuhan, China, is part of a family of viruses that our care teams are very familiar with. Coronavirus cause respiratory tract infections, including the common cold, and more serious infections like SARS. Symptoms start out like any other cold: fever, runny nose, cough and overall just feeling bad. It can progress and cause more severe illness like pneumonia, which can be fatal.

Evidence shows novel coronavirus is most often transmitted through droplets generated by coughs and sneezes. COVID-19 may also be transmitted when people touch contaminated surfaces and then touch their face, nose or mouth.

Symptoms may appear 2-14 days after exposure to the novel coronavirus, according to the CDC. People with these symptoms or combinations of symptoms may have COVID-19:

  • fever
  • dry coughs
  • shortness of breath associated with respiratory illness
  • muscle pain
  • headache
  • new loss of taste or smell
  • sore throat
  • chills
  • repeated shaking with chills
  • diarrhea

Sinus congestion or pain, nausea or vomiting are unlikely to be associated with COVID-19. Call your primary care provider if you experience symptoms and believe you have been in close contact with a person known to have novel coronavirus.

The Delta variant of the COVID-19 virus has prompted new warnings from health officials and even new lockdowns in parts of the world. It’s now the dominant strain in the United States and California. Experts are concerned because the Delta variant is more easily transmitted than previous strains of COVID-19. Epidemiologists say that people can shed the Delta variant longer, giving more chances for exposure. Vaccine manufacturers say that their COVID-19 vaccines still provide protection against this new variant, although no current vaccine is 100% effective.

There's no evidence that the new COVID-19 strains have any new symptoms or make people sicker. The case fatality rate won’t change, but if more people get sick because it’s more contagious, more people will die.

Pfizer/BioNTech announced that a preliminary study shows their vaccine is effective against these two COVID-19 mutations. Experts believe the Moderna vaccines will also be effective against the new coronavirus strains. More research is ongoing.

Learn more about the Delta variant from UC Davis Health

This new variant was first classified and named Omicron on Nov. 26 by the World Health Organization (WHO). Omicron was first discovered in South Africa. The variant has more mutations than any other variant that researchers have discovered. Many of the mutations are in the spike protein, which is what attaches to the cells and relates to how the virus is spread.

For this reason, all vaccines being used are focused on targeting and developing an immune response to the spike proteins. Health experts recommend that we all continue to help stop the spread of COVID-19 by being fully vaccinated, wearing a mask, staying home if you’re sick, washing your hands, and keeping your physical distance when around others.

Clinical pathologists, infectious disease physicians and scientists at UC Davis Health are collaborating on new reagents (substances used for chemical analysis) and diagnostic tests for COVID-19 that can be done in-house. The health system’s Clinical Laboratory began doing its own COVID-19 tests in March. The diagnostic laboratory team started using a new, high-capacity robotic testing instrument in early April. This commercial device has the ability to perform more than 1,000 tests for the novel coronavirus per day. In two months, UC Davis Health has performed more than 10,000 molecular tests. Learn more about our COVID-19 testing process here and how the test is conducted.

We don’t really know what the presence of antibodies means. It doesn’t necessarily mean that you’re immune to the coronavirus. Science has yet to determine what level of antibodies confirm immunity, if immunity is possible, or how long immunity might last. The result of a positive antibody test means nothing given the current gaps in knowledge about COVID-19. Until there is more definitive information, we should assume, even with positive antibodies, that a person may still be susceptible to the coronavirus.

You can get COVID-19 even after previous infection. Reinfection is rare within 3 months of initial infection, but immunity decreases over time. For an unvaccinated person after recovery from COVID-19, vaccination is recommended which reduces the risk of reinfection by more than 50%.

Common COVID-19 treatments include remdesivir, convalescent plasma, and dexamethasone. Remdesivir and convalescent plasma are used to control viral infection, and dexamethasone is used to control the immune response to infection. These drugs have often proven more successful than using a ventilator, which sometimes has made lung inflammation worse.

Yes, UC Davis Health is conducting multiple clinical trials related to novel coronavirus research. Those include an experimental treatment using the antiviral medication remdesivir for patients hospitalized with severe COVID-19 infection. If you are interested in participating in a COVID-19 clinical trial, visit the UC Davis Health Clinical Studies page.

COVID-19 affects everyone differently. There isn't necessarily a set amount of time in which people recover from novel coronavirus. However, the CDC’s guidelines on how long to stay at home in isolation are as follows:

  • If you think or know you have COVID-19 and have symptoms, you can be with others when the following three things are all true:
    • You've gone three days with no fever;
    • Your respiratory symptoms have improved;
    • And it's been 10 days since symptoms first appeared.
  • If you tested positive for COVID-19 but don't have symptoms, you can be with others if you continue to have no symptoms 10 days after your test.
  • If you've been around someone with COVID-19, you should stay home for 14 days after exposure, based on the time it takes to develop illness.

The CDC notes that in the first two cases, you might get tested to see if you still have COVID-19. If you are tested, you can be around others after you receive two negative test results in a row, at least 24 hours apart. For mild cases (outpatients), about two-thirds of people return to their baseline level of health within 2 to 3 weeks. It often takes longer to recover for patients with more severe disease who required hospitalization.

The CDC and FDA recommend a third dose Pfizer or Moderna COVID-19 vaccine or booster dose for the following groups:

  • people with compromised immune systems ages 5 and older (Pfizer is the only approved vaccine for ages 5-17.)
  • people ages 12 and older (Pfizer is the only approved vaccine for ages 12-17.)

Additionally, anyone who received a Johnson & Johnson vaccines is eligible for a second vaccine dose.

Schedule your booster or third dose through MyUCDavisHealth or California's MyTurn.ca.gov.

Yes. It’s important to know for several reasons:

  1. If your illness progresses, you’ll want to know so you can take advantage of treatments.
  2. You need to know whether to isolate so you can reduce your chances of infecting others, especially those who are more vulnerable to severe COVID-19.
  3. You will want to notify your loved ones and contacts so they can monitor themselves for symptoms and get tested if appropriate.

If you've been fully vaccinated against COVID-19 and have no symptoms, you do not need to quarantine if you've been in close contact with someone with COVID-19. Vaccinated people should get tested 5-7 days after close contact with a COVID-positive person, even if they have no symptoms. 

If you have not received a COVID-19 vaccine, the CDC recommends that you quarantine for 5 days after you've been exposed to someone who tested positive for COVID-19. You should then also wear a mask for an additional 5 days after your quarantine period is complete. You should also get tested to determine if you have COVID-19.

You should remain on the lookout for any COVID-19 symptoms for 14 days after exposure.

Yes. You can get reinfected after having COVID-19, although it is less common in the first 90 days after infection. The vaccines are not 100% effective, and breakthrough infections may occur.

However, if you have had COVID-19 and are then vaccinated, this decreases your chance of reinfection by about half. Also, protection wanes over time, which is why boosters are important. This is especially true for front line workers and those who are higher risk of complications, such as those with diabetes and respiratory illnesses.

Yes. Everyone should be masking (covering both the mouth and nose) when indoors around anyone not in their household and outdoors when in crowded situations. Several studies have indicated how effective masks can be in protecting yourself and others. It’s important to remember that you may be asymptomatic and not know you are infected but still able to spread COVID-19, so masking up in these situations helps to protect vulnerable people you could unknowingly infect.

California mandates that everyone, regardless of vaccination status, must wear a mask indoors in all areas. This includes in the following locations, according to the California Department of Public Health (CDPH):

  • public transportation (including airplanes, ships, buses, taxis, and rideshares)
  • K-12 schools
  • health care settings
  • long-term care facilities
  • state and local correction facilities and detention centers
  • homeless shelters

It’s difficult to estimate the protection from cloth masks since they aren’t standardized, but some studies suggest they are about 50% effective, compared to 60-70% for surgical masks and 95% for N95s. There is strong evidence that properly worn N95 masks are the most protective in terms of blocking transmission.

Cloth masks alone are not very effective against the most transmissible variants like Delta and Omicron. If an N95 mask is not available, a surgical mask covered with a cloth mask can be very effective.

Currently, there isn’t a study that shows increased protection from COVID-19 while wearing disposable gloves. Human hands have a lot of microbial, built-in defenses in the skin. COVID-19 can largely survive longer on gloves than it would on hands. The virus isn’t going to infect you through your hands, but rather because you touch your face, which can also happen while wearing gloves. In certain circumstances, wearing gloves is advised. For example, if you’re in contact with a surface that is likely infected, you can wear gloves and then take them off when you’re done. If you have problems with hand hygiene, like skin irritation from repeated washing, then wearing gloves (and changing to new ones often) is reasonable.

Don’t rely on gloves as a barrier to coronavirus, as your hands are probably more resistant to the virus than the gloves are. What’s most important is hand hygiene and not using your hands (gloved or not) to spread virus to your mouth, nose, eyes or ears.

You can reuse gloves – although they are inexpensive, and it’s recommended to use a new pair each time. However, the virus doesn’t last forever on a surface. After 7 days, the chance of the virus infecting you is very low. You can sanitize gloves with alcohol or wash them with soap and water.

COVID-19 and children

The Pfizer vaccine has received emergency use authorization from the U.S. Food and Drug Administration (FDA) for children ages 5-17. Moderna has begun testing the COVID-19 vaccine in children as young as six months.

Pfizer is the only approved vaccine for children ages 5-17. For those who are under 18 years old, they will need to have a parent or legal guardian provide consent for treatment at their appointment. UC Davis Health accepts written or verbal consent. It's also advised that anyone under age 18 have someone drive them to and from their appointment. With any vaccine, there's an increased risk of fainting for children ages 11 to 18, according to the CDC.

UC Davis Children’s Hospital, which is part of the Pediatric Emergency Research Networks, is one of the sites for a global study about COVID-19 in children. Pediatric experts are focusing on the risk factors that may lead to more serious forms of the disease, including a condition the CDC is now calling “multisystem inflammatory syndrome in children.”

This form of COVID-19 has been compared to toxic shock syndrome and to a very uncommon childhood illness called Kawasaki disease. It was described as “Kawasaki-like” in a recent article in the journal The Lancet. Physicians say the new syndrome seems to affect the heart more frequently than typical Kawasaki disease and has been identified mainly in school-aged children rather than infants or toddlers.

Fortunately, our children’s hospital has only seen a few pediatric COVID-19 cases. None of them have been as severe as what other parts of the country and world have seen.

Since May 2020, the CDC has been tracking multisystem inflammatory syndrome (MIS-C) in children. It is a rare but serious condition that can be life-threatening and require hospitalization, according to the California Department of Public Health. Some children developed MIS-C after being diagnosed with COVID-19 or after coming into contact with someone who had COVID-19.

According to the CDC, most cases are in children between the ages of 1 and 14 years. Children typically developed MIS-C 2-4 weeks after being infected with COVID-19. Symptoms of MIS-C include:

  • fever that doesn't go away
  • abdominal pain
  • vomiting
  • diarrhea
  • neck pain
  • rash
  • bloodshot eyes
  • feeling tired

Contact your child's physician immediately if your child has these symptoms.

Your health and medical care

If you need to go to the hospital because you are having a medical emergency, call 9-1-1 or get to a hospital immediately. If you have symptoms that are difficult to manage, but not that serious, call your primary care provider or seek urgent care.

If you have symptoms that seem like a common cold, but aren’t that serious, isolate yourself, treat it at home, and try not to share the infection with others.

Note: Some people are considered at higher risk for severe illness from COVID-19, according to the CDC. Some of these groups include people over age 65, and people of any age who have serious underlying medical conditions such as diabetes, chronic lung disease, serious heart conditions, or cancer treatment. The CDC currently advises higher-risk groups to:

  • Consult with your health care provider for more information about monitoring your health for symptoms suggestive of COVID-19
  • Have a plan for if you get sick, and
  • Call your health care provider if you do get sick

The CDC also posts specific information about other populations who need extra precautions, such as pregnant women and racial and ethnic minority groups.

If your symptoms or your medical condition are serious enough that you need medical assistance in managing your condition, then you should call your doctor, health care provider, advice nurse, or other health care professional.

Yes, please don't delay care. As in any hospital, there are many infection control and management measures in place at all times. We manage infectious disease, like novel coronavirus, every day in the hospital. We are here to care for everyone and to make sure everyone gets excellent care.

Visitors at UC Davis Medical Center:
Currently, we are restricting visitors within UC Davis Medical Center in order to help keep the novel coronavirus (COVID-19) out of the hospital.

Read more about our visitor restrictions

To reduce the spread of coronavirus, we are limiting the number of caregivers who can accompany patients during appointments at our clinic and medical office locations.

Learn more about our caregiver policy for outpatient clinics.

When people do visit us in person, we’re asking everyone questions as they enter the building. We’re screening for symptoms at entrances to all of our clinical locations, including our hospital, our outpatient centers, and our medical offices.

We are asking patients with symptoms of sickness to wear a mask in order to protect others. Care staff who assist these patients also wear protective equipment and use special procedures when needed to limit contact with other staff and patients (but not always – our infectious disease experts advise us when it’s necessary).

Read more about how we’re working to protect your safety — and how you can help

Our care teams are handling COVID-19 cases in much the same way we manage other diseases that require safety precautions and monitoring. We are in constant communication with the CDC, California Department of Public Health and Sacramento County Public Health about managing potential cases.

The information we receive includes best clinical practices for enabling clinicians, as well as patients and the public, to avoid being exposed to the virus.

Every person entering our care facilities is screened daily and required to report whether they have, or have recently experienced, specific kinds of symptoms. This is one of many ways we are making sure our health care workers are well and ready to carefully care for you.

Any employee with illness symptoms is expected to stay home until they are no longer contagious. It is in everyone’s interest to keep our workforce as safe and healthy as our patients.
