You Got the Second Dose of the Covid-19 Vaccine. Now What?
Celebrate your success and keep your mask on
As Covid-19 vaccines arrive in American cities, we are moving into a new phase of the pandemic. The vaccination rollout continues to improve, with the U.S. now vaccinating over one million people per day. Though millions still wait in line for vaccination access, 32 million Americans have received one dose, and over 9.5 million have completed the series.
Hope is on the horizon.
But Covid-19 is a novel virus with new vaccines and treatments, so it is not a surprise that many people have questions, especially about what to do after getting vaccinated. My mother, who qualified for vaccination in category 1B, prompted this story the morning after her second vaccine dose when she sent me this text:
Like millions of senior citizens, my mother is anxious to get out of the house and hug her grandchildren. Many others may be feeling the same way: Senior citizens and those with medical conditions are classified as 1B. Qualifications vary state by state but generally include those greater than 65 years old or with chronic medical conditions.
One important thing for vaccinated people to understand is that immunity does not come immediately after vaccination. It takes time for your body to build up protection. The two mRNA vaccines approved in the U.S. both require two doses. The first shot primes the immune system to produce protective antibodies. The second dose kicks it into high gear.
Here is what we know about post-vaccine immunity with the two Covid-19 vaccines currently available in the U.S.: In phase 3 clinical trials, the Pfizer vaccine showed a 95% efficacy seven days after the second dose. The Moderna vaccine offers 94% immunity at least 14 days after dose number two.
Two weeks after completing the vaccination course, recipients can breathe a sigh of relief. Their risk of severe disease from Covid-19 is very low. But we must remember that the risk is not zero.
