For now, distribution of COVID vaccines is according to a statewide plan.
For details of that plan, including who is in which phase and tier, see the links below. There is a statewide sign-up list to get the vaccine (use the first link), but some counties - including Santa Clara County - have set up their own lists as well (use the individual county links below to find yours).
Santa Clara residents can make an appointment to get the COVID vaccine at any one of several county locations using the links on this website.
Don't have internet access? Eligible residents can also make appointments for the County HealthSystem vaccine sites through the Valley Connection Call Center at 408-970-2000. The Call Center is open Monday through Friday from 7am to 9pm and Saturday and Sunday from 8am to 4:30pm. Assistance is available in English, Spanish, Vietnamese, and multiple other languages.
For details on who is currently eligible to be vaccinated, and where, around the Bay Area, check with your healthcare provider (if you have insurance) and with your county health authority.
Stadiums, fairgrounds, community centers, offices and local pharmacies are being added frequently as vaccination sites.
In the U.S., COVID vaccines are purchased with taxpayer funds, and are free - but there still might be an administration fee. (The full cost is covered for people without health insurance.)
In Santa Clara County, many vaccination locations are accessible by free public transit (VTA).
Information on the side effects of the vaccine, and precautions to take:
Getting vaccinated now does not mean we can immediately go back to our pre-pandemic life. The hope is vaccines will save lives and keep fewer people from getting seriously ill, but they probably will not be able to stop the pandemic in its tracks quite yet. It is not expected to provide sterilizing immunity like the smallpox vaccine does; it probably won't keep people from ever being infected. Instead we are likely to need to keep taking some precautions through 2021 (perhaps longer), to continue working to stop the spread.
Except, the CDC's Interim Guidelines allow relaxing those precautions when fully vaccinated people gather together in small groups with each other, and in other relatively low-risk situations:
After getting vaccinated (the first time, for 2-part vaccines, or after the 1-shot version), sign up with the CDC's reporting system to record your reactions, and help to push our knowledge of how to treat this novel disease forward.
Two vaccines were approved for use in the U.S. on Dec. 18, 2020, from the drug companies Moderna and Pfizer / BioNTech. A third, from Johnson & Johnson, was approved for use in the U.S. on Feb. 27, 2021.
They are very similar:
The first two from Moderna and Pfizer/BioNTech require two doses approximately a month apart (28 days for the Pfizer vaccine, 21 days for Moderna) to be fully effective. The Johnson & Johnson vaccine uses only one dose.
Most of us have a really basic idea of how vaccines work: by taking in a small dose of a relatively harmless version of a pathogen, our bodies create antibodies against that disease, so when we're exposed to infection, we are already equipped to fight it off. That's not wrong, but immunity is rather more complex. There are several different types of vaccines; depending on type and depending on the disease, each with their own limitations on how completely they can protect us and for how long.
To know what the vaccines currently in development for SARS-CoV-2 might give us, these resources can give us a better understanding:
How well our bodies resist infection - our immunity, in other words - depends on the strength of the antibodies created in our bodies and on how healthy we are overall. Active immunity (when our bodies create antibodies for ourselves) is stronger than passive immunity (when we are given antibodies from someone else) and also lasts longer. In the early days of this pandemic there was some hope that passive immunity transferred by blood plasma infusions from people who had recovered from COVID-19 would offer cures, but that turned out to be too unpredictable to be useful on a large scale.
Vaccine safety is a big concern to many in the U.S. There has been a lot of mis- and dis-information in the last decade on the topic of vaccines, especially vaccines for children. These sources will bust many of those myths:
The Centers for Disease Control and Prevention explains how they will make sure that the COVID-19 vaccines offered to the people of the U.S. are safe:
With familiar and well-known diseases like whooping cough (pertussis) or polio, we can measure the effectiveness of a vaccine, using past case history and statistics to figure out how many people were not infected because they got the vaccine, compared to unprotected people.
Effectiveness is impossible to calculate accurately for a new disease like the novel coronavirus. With COVID-19 the best we can do for now is measure efficacy (compare the number of cases in one group that got the vaccine, versus another control group that did not). And as one immunology textbook points out, when we look at vaccines, we are concerned with efficacy in three different areas:
The currently-available vaccines for COVID-19 are good at the last one, and also the second - but they don't offer sterilizing immunity.
Clinical trials testing efficacy of vaccines need to be as diverse as the population they intend to help. When there's only a small number of people participating in a clinical trial, though, it's hard to have confidence that it will work on more than a narrow slice of the population. The current clinical trials for COVID-19 vaccines being considered in the U.S. are paying attention to that problem; and the National Institutes of Health's All of US program aims to recruit larger and much more diverse groups of people to participate in all kinds of clinical trials, to avoid further bias in healthcare.
