The Centers for Disease Control and Prevention (CDC, for its acronym in English) suggested that people with certain health conditions that moderately or severely compromise the immune system they might need a fourth dose of the vaccine against Covid-19.
Among this group of people are those who are receiving treatment for diseases such as leukemia or cancerous tumors or HIV, as well as those who have received an organ or stem cell transplant, and those who take high doses of corticosteroids or other medications that suppress the immune system.
It is worth remembering that in the United States the CDC authorized that people with compromised immune systems receive a third dose of the biological against Covid-19, as long as they are older than 18 years, since this reinforcement improved the response of the antibodies in some sick people.
In this sense, the immunosuppressed could be eligible to receive the fourth dose of an mRNA vaccine against Covid-19 at least six months after receiving your third application.
The CDC explained that people with compromised immune systems who received a single dose of the vaccine Johnson & Johnson should be given a second dose a couple of months after the first, while those who choose the biological of Modern as a booster (even if they had a first dose from another brand), they should get another half dose as a booster.
Countries that already apply a fourth dose
The United States is not the first country in the world to bet on a third or fourth booster dose in vaccines against Covid-19; Since July, the Turkish authorities have offered people over 60 years of age and health personnel the option of a third dose of Sinovac or Pfizer.
Meanwhile, for Turkish people who have the need to travel abroad and verify that they are immunized with the drug from the German firm, the government also applies a new dose to strengthen the antibodies.
Meanwhile, other countries such as Israel, the application of a third dose for people over 50 years of the Pfizer / BioNTech vaccine is already authorized, but it is also considering the application of a fourth due to the increase in cases and the emergence of new variants of Covid-19.
