Newer COVID-19 variants are better protected by updated boosters

Information in Spanish


The flu vaccination is changed annually because the influenza virus is always changing. To help develop a better vaccine and, eventually, better protect people, influenza is being tracked globally. The brand-new, FDA-approved COVID-19 boosters operate under the same principle.

These upgraded boosters are designed to offer the best defence possible against the virus's most recent strains. The modified bivalent formula in the new boosters both strengthens immunity against the original coronavirus strain and guards against the more recent Omicron strains that are currently responsible for the majority of COVID-19 cases.

Everybody should get an updated booster as soon as they are qualified, according to the CDC. One explanation is that the fall and winter seasons often see an increase in COVID-19 cases. Because of the colder weather during these months, more individuals stay inside, which speeds up the spread of the illness. You will be better protected from the BA.4 and BA.5 Omicron lineages in the coming months with the help of an upgraded booster.

When will the COVID-19 booster be updated?

The new COVID-19 boosters from Pfizer-BioNTech (for those over the age of 12) and Moderna (for those over the age of 18) are free and easily accessible in local health departments and retail pharmacies across the United States. A local vaccine provider can be located.


Whether it has been two months since your last booster dosage or after finishing the primary
vaccine series, you should obtain the booster at least two months after your last COVID-19 shot. To find out when to get your booster, utilise this online calculator.


The updated booster takes the place of the initial (monovalent) booster for individuals 12 years of age and older. The original booster is still available for kids aged 5 to 11.


Suppose I had COVID-19. Do I need a booster now?

Even if you've received COVID-19, the CDC advises taking the latest booster for extra protection. This is due to the fact that natural immunity differs from person to person and declines with age. Three months following a positive viral test, it is advised that you get a booster shot.


Immune system compromised I need to acquire the booster soon.

For those who are moderately to severely immunocompromised, the CDC offers updated recommendations for the COVID-19 vaccine and booster shots (see CDC list for qualifying medical conditions). To find out when to get your booster, utilise this online calculator. To find out whether a booster shot or increased dose is required at this time, it is advised that you first speak with your specialist provider.


How effective are the upgraded boosters?

Numerous studies have demonstrated that COVID-19 vaccine effectively prevents the disease's worst effects, including serious illness, hospitalisation, and death. These investigations also demonstrate a progressive loss of vaccination protection.Because of this, some vaccine recipients still develop mild to moderate COVID-19.

However, research also demonstrates that supplements strengthen our immune response and offer further disease protection. 

There is further proof that upgraded boosters made to guard against more recent virus strains offer even more COVID-19 protection than the initial boosters. 

Public health officials won't completely understand the effectiveness of the new updated boosters until they can assess how well people are protected against virus strains that are currently in circulation.


We may occasionally require new
COVID-19 boosters that are designed to protect against the virus causing the majority of COVID-19 cases at that time, similar to having an annual flu vaccine.
