When are you fully vaccinated

You should get your second shot as close to the recommended 3-week or 4-week interval as possible. You should not get the second dose early.

Most people who get COVID-19 are unvaccinated. However, since vaccines are not 100% effective at preventing infection, some people who are fully vaccinated will still get COVID-19. An infection of a fully vaccinated person is referred to as a “vaccine breakthrough infection.”

The ideal time frame between the first and second Pfizer vaccines is 21 days. For the Moderna vaccines, it’s 28 days. It’s very important to check with your vaccine site or local health department about scheduling your second vaccine, because different sites are handling scheduling differently.

Side effects from both the Moderna and Pfizer COVID-19 vaccines are more common after the second dose. This is because your immune system recognizes the virus spike protein from the first dose of the vaccine and mounts a stronger response.

They are also more likely to occur in women who are enceinte or on oral contraceptives, or in people who have hereditary disorders that predispose them to blood clotting. As mentioned above, the clotting condition associated with the J&J vaccine is called thrombosis with thrombocytopenia (TTS).

For example, the Moderna vaccine’s side effects last roughly 1 to 3 days for most people. If your symptoms last longer, get worse, or you develop new symptoms, like a cough, you should get medical care right away.

It is normal to feel sick after getting a COVID-19 vaccine.
You may have a sore arm.
Put a cool, wet cloth on your sore arm.

November 08, 2021 If you experienced side effects when you were vaccinated initially, you may wonder if you’ll have any noticeable symptoms in response to your booster shot. While you may have some side effects, they should be no worse than what you experienced originally and may well be milder.

Both the Pfizer and the Moderna COVID-19 vaccinations involve two injections separated by several weeks. For these two-shot vaccinations: If you had COVID-19 before being vaccinated, the first injection may cause more noticeable side effects than for people who have not had the coronavirus.

Booster shots are given to people who are likely to have developed a strong immune response with prior vaccination, in order to help increase, or boost, the immunity they already have. This is because there is some evidence from clinical trials that antibodies produced after the first two shots decline over time.

In the case of Moderna, the booster dose is only half of the original dose. Unlike boosters, third/additional doses of COVID-19 vaccines are for people who received the complete starter series of vaccines but then their immune systems didn’t have a good enough response.

CDC is adjusting our recommendation for when people can receive a booster shot, shortening the interval from 6 months to 5 months.

A new study from the Center for Disease Control and Prevention confirms what Mayo Clinic and other experts have been saying: COVID-19 booster vaccinations improve protection against severe illness and hospitalization.

The FDA has authorized three vaccine boosters — Pfizer-BioNTech, Moderna and Janssen/Johnson & Johnson — and determined that it is safe to get a COVID-19 vaccine booster or additional dose that is a different brand than your initial dose or doses.
