Those who need the 4th dose of Covid-19 vaccine

If you’ve had 2 doses of the vaccine plus a booster, you may be wondering if you need a 4th dose – especially in light of the recent news of the rising number of Covid-19 cases.

Vaccine manufacturers appear to be prepared for the need for a second booster dose. Moderna is asking the Food and Drug Administration (FDA) to approve the supplement for all adults. Pfizer recommends that US authorities give more doses to adults 65 years of age and older.

Meanwhile, the US Centers for Disease Control and Prevention (CDC) recommends that some teenagers and adults get a second booster shot.

But some experts stress we still can’t say for sure if a fourth dose is necessary for everyone.

Subjects needing the 4th dose of vaccine

The CDC has recommended a 4th dose of Pfizer or Moderna vaccine for people over 12 years of age with moderate to severe immunodeficiency. This includes people with cancer, primary immunodeficiency or being treated with immunosuppressive drugs.

The US health agency has not made a decision to give booster doses to other groups of infants, adolescents, and adults or to immunocompromised children under 12 years of age.

Dr. Vivek Cherian explained, 3 doses of the vaccine still very well protect against severe illness, hospitalization and death. He said the FDA and CDC will review the data to determine if a fourth dose is needed for other groups.

Some early analyzes found the fourth dose to be “somewhat effective” for symptomatic disease. But more research is still needed to determine how the fourth dose will work and how long it will work.

Those in the group recommended a 4th dose at least 3 months after the 3rd dose of Pfizer or Moderna vaccine.

To date, it is not clear whether the fourth dose will work with new variants such as Deltacron. The US CDC states: “Available vaccines are expected to protect people from severe illness, hospitalization, and death from Omicron infection. We still don’t know how effective the vaccine will be against these complications,” said the CDC. new body (like Deltacron)”.

CDC plans to monitor the effectiveness of the vaccine on variations in real-world conditions.
