Researchers are moving fast to develop vaccines to combat Covid-19. In the past, it would take years to bring a new vaccine through all the regulatory hurdles established by the Food and Drug Administration (FDA) and to approval.
According to the Centers for Disease Control and Prevention (CDC), it can take a few weeks for your body to build up antibodies and maximize Covid-19 protection after receiving the second dose of the vaccine. That's why wearing masks, social distancing, practicing hand hygiene and avoiding large…
The Pfizer-BioNTech Covid-19 vaccine demonstrated 52 percent efficacy in protecting against disease after the first dose, according to the clinical trial data. The Moderna vaccine demonstrated 80.2 percent efficacy after the first dose. To maximize the protection from these vaccines, it is…
The federal government has taken steps to deliver a future vaccine for Covid-19 at no cost to individuals and families during the pandemic. This is the way vaccines have been made available to the public in previous health emergencies.
With vaccine development moving so quickly, it’s easy to understand why some people are asking whether a vaccine for Covid-19 will be safe and effective. But it is important to remember the very strict scientific and regulatory process vaccine developers must follow to bring a new product to…
Scientists have not yet figured out how much immunity (protection from an infectious disease) people have after recovering from a natural case of Covid-19, or how long natural protection lasts. Some early studies suggest that natural immunity may fade more quickly in certain people. That may be…
While not considered to be at high risk for severe complications from Covid-19, serious cases do occur among younger, healthier people. The Centers for Disease Control and Prevention (CDC) also warns of the potential long-term health effects of Covid-19 infection, even for those who experienced…
Monoclonal antibody treatments are not the same as vaccines. Monoclonal antibodies are medicines that directly deliver man-made antibodies against a virus to your body to help fight off infection. To treat Covid-19, the FDA has approved two monoclonal antibody treatments for emergency use --…
The simple answer is, yes. All vaccines – even those developed in response to a pandemic like Covid-19 – must follow the Food and Drug Administration’s strict scientific and regulatory requirements.
To measure vaccine efficacy, or how well a vaccine works in a controlled clinical trial, the Food and Drug Administration (FDA) first looks at the number of people who fell ill with the disease. Then the agency compares whether they received the vaccine or the placebo (a harmless, inactive…
