How protected am I from Omicron, based on the Covid-19 vaccine you have? This is the information we have so far. The rapidity with which the Omicron variant has spread in the world has concerned health institutions, due to the more than 50 mutations it has accumulated.
Vaccines against
Covid-19 have shown protection against the most serious pictures of the disease, that is why the booster dose has begun to be applied in Mexico to adults over 60 years of age.
The protection of the vaccine against the Omicron variant remains under investigation, so far there is not enough information yet.
How dangerous is the Omicron variant and what are the symptoms?
The new variant of the coronavirus remains dangerous due to the high spread worldwide, however, the fact that this variant accumulates more mutations does not make it more aggressive or more lethal and no more deadly than the delta. The symptoms that may occur are unusual but mild:
- Extreme fatigue (the most commonly identified symptom)
- Muscle pain for a few days
- Smell and taste are not lost
How do vaccines protect against the new variant of Covid-19 and which is the best?
Pfizer
The first analyzes that were made on this vaccine showed that the protective effect decreases drastically against the new variant, so a booster dose will increase the defense of the immune system. Pfizer provides only 33 percent protection against infection, but offers 70 percent protection against hospitalization.
Moderna
The executive director of the American pharmaceutical company reported that the Moderna vaccine could not be as effective against the Omicron variant. Company president Stephen Hoge indicated that current vaccines are likely not resistant to the variant, but argued that the booster dose may offer some protection against serious infections.
AstraZeneca
The American pharmaceutical company has also had few studies because the variant was detected last November, one of the reports that has been released by the United Kingdom Health Security Agency showed a sharp drop in the effectiveness of the vaccine.
Johnson & Johnson
The Omicron variant has an ability to evade a group of defenses, so this vaccine has also not shown protection against the new variant, but Mathai Mammen, the company's global director of research and development, reported that it has already begun to develop a Omicron vaccine.
Sputnik V
The vaccine developed in Russia has a high neutralizing activity against the coronavirus variant, as mentioned by the Gamaleya Institute of Russia. The World Health Organization has not yet accepted this vaccine.
The investigations are still in process, as well as it is affirmed that a single dose of the Sputnik Light vaccine would achieve an efficacy of 80 percent against the variant, there are other studies that show the opposite; that produces little or no antibodies.
Cansino
The Chinese pharmaceutical company that produces the Cansino or Sinopharm vaccine has not yet released information on its efficacy against the variants, however the WHO indicated that current vaccines are still effective against serious infections and death. "
All pharmaceutical companies continue with research on the Omicron variant, so a final verdict on the efficacy of Covid-19 vaccines against the variants cannot yet be reached.
