Information on subunit protein vaccines against COVID-19

Protein subunit vaccines against COVID-19 have undergone rigorous safety testing

Vaccines against COVID-19 are safe and effective.

Vaccines with protein subunits against COVID-19 have been subjected to the same stringent safety and efficacy standards than all other types of vaccines in the United States. The only COVID-19 vaccines that the Food and Drug Administration (FDA) makes available in the United States (through its approval or emergency use authorization) are those that meet these standards.

Protein subunit vaccines have been used for years

More than 30 years ago, the hepatitis B vaccine became the first subunit protein vaccine to be approved for use in people in the United States. Another example of protein subunit vaccines currently used in the United States includes acellular pertussis vaccines.
