In emergencies, the experts at the FDA can decide that the benefits of a drug justify a shorter process. If so, the FDA can issue an Emergency Use Authorization (EUA). Under an EUA, the FDA maintains its strict standards but makes decisions more quickly than usual.

Herd immunity exists when so many people have been infected and become immune—or immunized by vaccination—that the chain of infection is broken.
Even though both vaccines can be given at the same visit, people should follow the recommended schedule for either vaccine: If you haven't gotten your currently recommended doses of COVID-19 vaccine, get a COVID-19 vaccine as soon as you can, and ideally get a flu vaccine by the end of October.

The COVAX Facility is the global pooled procurement mechanism for COVID-19 vaccines through which COVAX will ensure fair and equitable access to vaccines for all 190 participating economies, using an allocation framework formulated by WHO.
Herd immunity', also known as 'population immunity', is the indirect protection from an infectious disease that happens when a population is immune either through vaccination or immunity developed through previous infection. WHO supports achieving 'herd immunity' through vaccination, not by allowing a disease to spread through any segment of the population, as this would result in unnecessary cases and deaths.
See full answerWe are still learning about immunity to COVID-19. Most people who are infected with COVID-19 develop an immune response within the first few weeks, but we don’t know how strong or lasting that immune response is, or how it differs for different people. There have also been reports of people infected with COVID-19 for a second time. Until we better understand COVID-19 immunity, it will not be possible to know how much of a population is immune and how long that immunity last for, let alone make future predictions. These challenges should preclude any plans that try to increase immunity within a population by allowing people to get infected.
Herd immunity happens when a large part of the population -- the herd -- is immune to a virus. This can happen either because these people got vaccinated or had already been infected. Herd immunity makes it harder for a virus to spread.So even those who haven't been sick or vaccinated have some protection.
Yes. It is possible have flu, as well as other respiratory illnesses, and COVID-19 at the same time. Health experts are still studying how common this can be. Some of the symptoms of flu and COVID-19 are similar, making it hard to tell the difference between them based on symptoms alone.
“Don't wait for a better vaccine, because you leave yourself vulnerable,” Talaat says. “Get what boosters you're eligible for now, and then you will have the opportunity to get another booster that may provide broader protection in the fall.”
It is not recommended you take over-the-counter medicine (such as ibuprofen, aspirin, or acetaminophen) before vaccination for the purpose of trying to prevent vaccine-related side effects. It is not known how these medications might affect how well the vaccine works.
