Second COVID Vaccine Shot Side Effects

The video explains the side effects of COVID-19 vaccines, emphasizing that stronger reactions after the second dose indicate a robust immune response. It details how vaccines work by teaching the immune system to recognize pathogens, leading to both innate and adaptive immunity. Clinical trials show more intense side effects after the second dose, but these are temporary and less severe than COVID-19 itself. The video also discusses the potential for those who have recovered from COVID-19 to require only one vaccine dose, based on preliminary studies.
