Entering our fourth pandemic year, with over a million U.S. deaths and plummeting life expectancy, we now have safe, effective, even if imperfect Covid-19 vaccines. Unprotected by vaccination, however, people are returning to routine behaviors: mingling, vacationing, and going to stores, schools, and workplaces. Covid-19 is still not routine like the common cold. Being fully vaccinated, and practicing masking and distancing, remain important. With Covid-19 rampant, individual immunity is essential for individual protection. Only vaccinated or recently infected individuals will be protected. Individuals cannot avoid contracting Covid-19 by assuming that others’ immunity has made the virus rare. Improved vaccines including nasal vaccines may become available soon. Vaccination also might accelerate, and infection decelerate as factors contributing to population protection.
