Why some vaccines need boosters and others don’t-Doha News

To date, Gulf countries have managed more than 331,437 Moderna and Pfizer booster effectsBut why do you need it?

The COVID-19 (new coronavirus infection) The virus has produced 11 variants so far, with Delta and Omicron being the two most contagious. British researchers amplifier Shots can have an 85% protection impact on severe illnesses of the Omicron subspecies.

Pfizer has also released result From the first study showing that the third dose of the COVID-19 vaccine increased antibodies against the new mutant 25-fold when compared to the second dose. Therefore, experts agree that booster shots are available and should be taken as soon as they are qualified.

Nevertheless, the deployment of booster vaccines has caused controversy around the world among those who dislike vaccines. In general, some people still oppose vaccines and appear to confuse side effects with side effects, and / or believe they simply don’t need a vaccine because they are young and healthy. ..

A recent controversy over boosters seems to be that “if booster shots are needed on a regular basis, that means the vaccine doesn’t work.”

But this is not just true. Just because a booster is needed does not mean that the vaccine will not work, but that the protection it provides will gradually wear out and need to be “replenished”.

Scientific data have already demonstrated the effectiveness of these vaccines and their effects on infection, hospitalization, and death.

What science has taught us about the COVID-19 vaccine and the protection they provide is that the protection begins to weaken slightly 6-8 months after the second dose of the vaccine, and booster shots need to be reminded. It means that there is. Reignite the immune system.

What people don’t really understand is that this isn’t the first time this has happened in medicine. In fact, booster shots are very common and many vaccines require several doses to immunize.

The need for booster shots is highly dependent on the type of vaccine being administered. Most vaccines that do not contain live viruses usually require multiple doses or boosters.

On the other hand, a single dose of some live vaccines can provide lifelong protection against the target disease. Other live vaccines may require two doses, including measles, mumps, and rubella (MMR) vaccine.

Some types naturally require several doses to give overtime to be effective, and the chance is likely that you have already received them in your lifetime. The tetanus vaccine is one example.

The tetanus vaccine is the recommended series of immunizations in childhood and adulthood and should be given every 10 years to protect against Lockjaw.

It is recommended to take other vaccines every year, such as the influenza vaccine and hepatitis A vaccine, which Qatar’s Ministry of Public Health (MOPH) recommends to take every year from 12 months of age.

Other common vaccines that require boosters are:

  • A pneumococcal conjugate vaccine given three times. It protects against pneumococcal infections caused by a type of bacterium called pneumococcal that can cause serious life-threatening infections, including pneumonia, bacteremia, meningitis, and acute otitis media.
  • Polio vaccine is also given three times by the age of 18 months, and booster immunization is given at the age of 4 to 6 years, depending on the type of vaccine used.

Given the fact that the COVID-19 virus and its associated vaccines are still relatively new, scientists are still learning about the duration of protection provided by these vaccines. Over time, we will be able to make very accurate predictions, which in turn will lead to better health results.

However, what makes this process difficult is the emergence of new variants. The term of protection depends on several factors, one of which is the rate at which the virus can replicate.

If the virus replicates quickly, more variants will occur. The emergence of these variants makes it increasingly difficult to produce vaccines that sustain immunity as the target continues to move. If the virus is stable, it gives scientists the advantage of being able to predict persistent immunity.

Measles is an example of a stable virus that is unlikely to replicate, and as a result, the measles vaccine provides long-term immunity. Similarly, smallpox and polio are highly contagious viruses that are stable and have low mutation rates, and have been largely eradicated by immunization.

The most common example of a virus that replicates and mutates frequently is the influenza virus, which occurs in multiple strains each year. For this reason, this season’s flu vaccine provides precautions against strains that differ from the previous year or the following year, so it is recommended that you be vaccinated against influenza each year.

MOPH in Qatar has recently made walk-in booster shots available without prior reservation due to a surge in domestic incidents and the latest developments under the Ehteraz regulations.

Everyone recommends taking a third dose. Also, do not forget or ignore other precautions such as wearing a mask, social distance, and hand hygiene.
