Vaccine experts yesterday started discussing if there may be a possible need for a third vaccine required for the COVID-19 virus. Pfizer has a two-dose process that has proven to be very effective, but scientists are already predicting the virus will have mutated into several more types and strains of infection that will not be covered with the current vaccine mixture. The Company said they believe there will be a need for a booster shot in 8 to 12 months which would be late in the year and early next year. Clinical tests are underway.
