Pfizer-BioNTech and Moderna Vaccines
The mRNA vaccines come in two doses. The first dose of the vaccine helps prepare your immune system and the second dose provides most of the immunity. Once you receive both doses of the vaccine, it will likely take several weeks for your body to develop immunity. Both doses are important to ensure full protection.
Booster shots for the mRNA vaccines will soon be available.
On 8/18, HHS put out the following statement:
We are prepared to offer booster shots for all Americans beginning the week of September 20 and starting 8 months after an individual’s second dose. At that time, the individuals who were fully vaccinated earliest in the vaccination rollout, including many health care providers, nursing home residents, and other seniors, will likely be eligible for a booster. We would also begin efforts to deliver booster shots directly to residents of long-term care facilities at that time, given the distribution of vaccines to this population early in the vaccine rollout and the continued increased risk that COVID-19 poses to them.
Additional Dose for Immunocompromised Patients
The CDC recommends people who are moderate to severely immunocompromised should receive an additional dose of mRNA COVID-19 vaccine after the initial 2 doses.
Currently, CDC is recommending that moderately to severely immunocompromised people receive an additional dose. This includes people who have:
People should talk to their healthcare provider about their medical condition, and whether getting an additional dose is appropriate for them.
