I believe we are no strangers to the Delta strain.
The mutant strain discovered for the first time in India is almost as if it has been opened, breaking through several layers of human defenses and completely shattering the desire to "use a vaccine to completely eliminate the new crown
.
" However, "Delta" was making the world frightened, and the new crown mutant strain "MU" arrived quietly, which undoubtedly made the new crown epidemic worse
Delta variant makes the world frightened, "MU" strikes again
Delta variant makes the world frightened, "MU" strikes againThe new crown mutant strain "MU" was first discovered in Colombia in January 2021 and was named B1621
.
So far, it has been found in 39 countries including Latin America and Europe
The strain has a mutation called P681H that will make it spread faster, but the study is still in a pre-printed state and needs to be formally reviewed, so it is not yet possible to determine the effect of this mutation on the behavior of the virus
.
The other two mutations of the "MU" strain, E484K and K417N, may help it escape the attack of antibodies, because these mutations also appear in the delta variant, causing some vaccines to fail
Israel plans to start the fourth shot of the new crown vaccine
Israel plans to start the fourth shot of the new crown vaccineNo matter how the virus changes, injecting the new crown vaccine at this stage is still an important means to prevent infection
.
When many countries are still struggling when the third dose of the new crown vaccine will be vaccinated, is it necessary to vaccinate? The relevant Israeli experts have already started planning for the fourth shot!
As the first country in the world to officially provide the third dose of vaccine, as of now, 2.
5 million Israeli citizens have completed the third dose of COVID-19 injection, accounting for nearly a quarter of the country’s 9.
3 million population.
Vaccine protection effectiveness, on July 30, Israel launched a "strengthening injection" program in people over 60 years of age
.
According to data released by Israeli officials in mid-August, compared with the overall protection effect of 10 days after two doses of vaccination, the overall protection effect after 10 days of booster vaccination for people aged 60 and over in Israel is 4 times higher; In other words, the effect is 5 to 6 times better!
In the future, the Israeli government will organize citizens to prepare a fourth dose of the new crown vaccine to effectively prevent the new crown virus variant, but the specific vaccination time has not yet been determined
.
It is understood that considering that the new variant will weaken the efficacy of the vaccine, Israel will receive the fourth dose on the 7th day after the completion of the third dose of the new crown vaccine, in order to effectively improve humoral and cellular immunity
