This is because the original need for three shots, but now only one shot is needed, which led to the overall decline of the stock. Zhifei closed down 14% and Wan Tai Bio fell 9.4%, both of which were related to vaccines. Negative for Zhifei Bio means that the head office issued an additional 3 billion yuan in one day, and even with the company's fund, there was a loss. Some people have said that they only need one shot, but they have taken three shots of HPV vaccine. If they had known, they would have taken two fewer shots. But this situation is only part of the region. There is no way to cover the whole world. The stocks affected by this also fell across the board.

HPV vaccine at the same dose can effectively prevent cervical cancer caused by HPV infection. And it must be two-level or three-level vaccination to be effective. Cervical cancer is completely preventable, but not everyone can get equal opportunities. We know that cervical cancer is caused by HPV virus, which is one of the fourth most common diseases in China. HPV vaccine is beneficial to these two viruses. There are 5 kinds of HPV vaccines available in the world. From the point of view of the industry, if the who's suggestion can be implemented, the whole rules of HPV disease prevention will change, which will be a big impact on HPV enterprises. The vaccine immunization program recommended by WHO still has a long time to go, and its market influence on the stock of HPV vaccine in China is relatively small, and its impact on the profitability of enterprises is also relatively small. The single dose of HPV vaccine is equivalent to two doses and three doses, and this news makes the stock decline only temporary.

It's only because it seems that the cost is lower and the amount of resources occupied is less, which makes it easier for consumers to accept. However, due to the different age groups, the supplementary things are different and the management levels are different. So it doesn't mean that one dose is better than three doses. And now the world is almost hard to find. Therefore, 3 stitches are within the acceptable range.
