The spike protein then stimulates immune responses. The SARS-CoV-2 gene that creates the spike protein is inserted into a harmless virus to deliver the gene to human cells. It is in Phase 3 clinic trials in the U.S. This type of vaccine is also used for whooping cough (pertussis) and hepatitis B. Harmless pieces of SARS-CoV-2 spike protein are used to make this vaccine. These vaccines are authorized for emergency use in the U.S. Once the body does this, it then discards the mRNA. This type of vaccine trains our body to recognize and fight the protein. The SARS-CoV-2 gene that creates the spike protein can be used in the form of DNA or messenger RNA (mRNA) as a vaccine. The third kind are Vector vaccines, the vaccines manufactured by AstraZeneca and Johnson & Johnson use this approach. The second type are Protein vaccines, the vaccine being produced by Novavax uses this approach. The first kind are RNA vaccines, the vaccines manufactured by Pfizer and Moderna use this approach. ![]() There are three types of vaccines against SARS-CoV-2, the virus that causes COVID-19. It must be at least two months since you received your vaccine andĪppointments are available at UW Medical Center – Montlake, Harborview and UW Medicine primary care clinics.If your initial vaccine series was Johnson & Johnson If your initial vaccine series was Moderna It must be at least five months since you completed your primary vaccine series and.If your initial vaccine series was Pfizer They are also recommending third doses for those who received the Johnson & Johnson/Janssen vaccine - the original dose followed by a second dose of Pfizer-BioNTech or Moderna (mRNA COVID-19 vaccines) at least four weeks (28 days) after the first dose, plus a booster (either Pfizer-BioNTech or Moderna) at least two months after the second dose. Food and Drug Administration (FDA), your booster is not required to be the same COVID-19 vaccine as the one you received in your initial dose(s).įor those who are immunocompromised, the CDC has updated its recommended intervals between the primary series and booster shots from five months to three months. Moderna, Johnson & Johnson and Pfizer boosters are now available to all patients who meet eligibility requirements. ![]() Visit King County’s COVID-19 vaccine webpage for other appointment options.įor more information, visit our child vaccine pageĪ booster is an additional shot that helps to extend the vaccine's' effectiveness and maximize your protection from COVID-19 infection. However, we are happy to vaccinate your child if needed. If your child’s primary care provider does not treat patients at one of the clinics listed above or is outside UW Medicine, we recommend that you check with them for scheduling. ![]()
