Like Pfizer, it contains mRNA that gives instructions for fighting the spike protein on the COVID-19 virus. The Moderna vaccine, also called Spikevax, is an mRNA vaccine OverviewĪlthough it works similarly to the Pfizer vaccine, it delivers a slightly higher dose. A 2022 study found that in a lab setting, a booster could offer some immunity to Omicron.

Preliminary data from Pfizer showed that three doses of the vaccine could neutralize the Omicron variant. This time period extends into the Delta wave of the pandemic. In children ages 5–15 and people with immunocompromising conditions, the vaccine was at least 90% effective.Īmong adults without immunocompromising conditions between March 11 and August 15, 2021, the vaccine offered 88% efficacy against hospitalization.

EfficacyĪccording to the CDC, the full series of the vaccine is more than 95% effective at preventing laboratory-confirmed COVID-19 infections in adults who are not immunocompromised and have no documented history of a COVID-19 infection. They happen because of the immune system’s reaction to the injection, so having side effects shows that the vaccine is working. The side effects usually disappear within a few days. They commonly report cold and flu-like symptoms such as: The vaccine’s side effects are typically mild, and some people report having more side effects after the second vaccine. It is safe to mix and match this vaccine with others. Ages 5-11: two 0.2 milliliter (mL) doses.The initial series is two injections, at least 21 days apart, and a booster requires a third shot. It has an emergency use authorization for people over the age of 5 and for booster shots. The FDA has approved the vaccine for individuals over the age of 16. The vaccine’s contents leave the body and do not alter a person’s genetic code.

The vaccine teaches the body how to fight the COVID-19 virus when it encounters the real thing. The body responds to this spike protein as an intruder and develops the immune reaction it needs to fight it. However, it does not contain the virus - rather, it contains a piece of messenger RNA (mRNA) that codes for the virus’s unique spike protein. It uses a lipid, or a fatty acid, to deliver a piece of the virus’s genetic code. The Pfizer-BioNTech vaccine, also called COMIRNATY, is an mRNA vaccine. Read more to learn about the approval status, dosage, efficacy, and side effects of each COVID-19 vaccine. While there have been rare instances of serious side effects, the risk of adverse events from a COVID-19 infection is much higher. The data on COVID-19 vaccines show that side effects are minimal. Like all medical treatments and medications, vaccines come with risks and benefits. Many countries are starting to approve the new Novavax vaccine and the Oxford AstraZeneca vaccine that is common in Europe. However, different vaccines are available globally. The Centers for Disease Control and Prevention (CDC) recommend getting Moderna or Pfizer-BioNTech if they are available. The Food and Drug Administration (FDA) has approved or authorized three vaccines: Moderna, Pfizer-BioNTech, and Johnson & Johnson’s Janssen.
