Omicron variants BA.4 and BA.5 invaded Taiwan for the first time, and the command center confirmed that 5 cases were intercepted at the border. Since these two mutant strains have high infectivity and immune escape characteristics, they are more likely to be re-infected. Fortunately, the severe and fatal rates have not increased particularly, but they are afraid that the epidemic will rise again in the future. Experts also recommend that in autumn and winter Take the fourth dose to avoid the next wave of the pandemic.
The Taiwan border was once again breached by Omicron. The command center confirmed that, for the first time, there were 4 cases of new subtype variants BA.5 and 1 case of BA.4, which have been popular in foreign countries for a while, and the transmission ability Stronger than the current mainstream BA.2 in Taiwan.
Huang Limin, director of National Taiwan University Children’s Hospital, said, “The main advantage of BA.4 and BA.5 is that they are less afraid of the original antibodies, so it turns out that if you are vaccinated or naturally infected, you will encounter BA.4 and BA.5. Easy to re-breakthrough infection.”
Gong Yunong, an assistant researcher at the Chang Gung University Infection Research Center, said, “What everyone may care about is, for example, similar pathogenicity, etc., but it is still under research, and it is not said that it is more pathogenic, or that it has any special clinical features. reaction or something, because it’s an upper respiratory infection.”
The transmission power of BA.4 and BA.5 is 20~30 percentage points higher than that of BA.1 and BA.2, but the severe and fatal rates have not increased, but everyone is starting to worry that when the weather gets colder in autumn and winter, Taiwan may cause A new wave of community pandemics, experts believe that the fourth dose is indispensable.
Jiang Guanyu, a physician from Beijing Union Medical College, said, “The titers of BA.4 and BA.5 are the same as BA.2 antibodies, which is 1/4.2 of that of BA.2, because the antibody titer of the third dose is less effective for BA.4, BA. BA.5 is still not enough, it turns into saying that they will continue to play the fourth dose.”
Huang Limin, director of the National Taiwan University Children’s Hospital, said, “The probability of the epidemic returning at the end of the year is actually quite high, because of our immunity, whether it is this wave of infection or the three doses of the vaccine we took before, it will start in three months. It’s unreliable, the weather is getting cold, and if other countries start heating up, we probably won’t be able to run away.”
Taiwan currently has an infected population of about 2.86 million, mainly BA.2. The people themselves already have antibodies, and they still have a certain degree of protection against BA.4 and BA.5. As long as the vaccine is fully filled, it is also a virus of the Omicron branch. In other words, even if there is a pandemic in autumn and winter, it will not be as severe as the wave in May this year (2022).
