Pfizer says a third vaccine shot would “strongly” boost protection against the highly contagious Delta variant. The company cited new data that suggests a third shot could improve immune response by up to five times more in people ages 18-55, and eleven times more in people over 65. Pfizer is currently seeking FDA approval for a third booster shot, which would potentially be administered 12 months after the second dose. Do you think a third dose is necessary? Will COVID vaccines become an annual thing like flu vaccines?
