[Ming Pao News]The latest US study found that the level of antibodies produced by injecting the COVID-19 vaccine booster and the flu vaccine at the same time was higher than taking the two vaccines separately. (Editor’s note: In addition, the Omicron XBB lineage variant strain of the new coronavirus is currently prevalent in Hong Kong. According to Xu Shuchang, chairman of the Scientific Committee on New Discovery and Animal Infectious Diseases, the Forbitac XBB vaccine will arrive in Hong Kong early next month. Member of the Scientific Committee on Vaccine Preventable Diseases Kong Fanyi, director and clinical professor of the Department of Infectious Diseases, Department of Medicine, Faculty of Medicine, HKU, predicts that Hong Kong will enter the peak period of the new crown epidemic in December, and it is recommended that the elderly and high-risk individuals receive the XBB vaccine.)
A U.S. study found that simultaneous vaccination with the bivalent COVID-19 vaccine and influenza vaccine increases the number of antibodies against both viruses
This study (13th) was published at the annual vaccine summit in Boston. Two groups of medical staff in Massachusetts were tested. The first group of 12 people received a booster dose of the new coronavirus bivalent vaccine and a seasonal influenza vaccine at the same time. A group of 30 people were vaccinated against COVID-19 and influenza on different days within the same month. The researchers then measured the antibody levels of the two groups of people and found that those who received both vaccines at the same time had higher levels of “immunoglobulin G1” (IgG1), which is an antibody against the new coronavirus and influenza viruses. This research has not yet been peer-reviewed.
Amesh Adalja, a scholar at the Johns Hopkins University Center for Health Security, said that this is an interesting finding, possibly because vaccination with two vaccines at the same time increases the stimulation of the immune system, but believes that the key is whether higher levels of antibodies will translate into Greater protection from infection.

Fewer side effects than just a COVID-19 booster shot
The U.S. Centers for Disease Control and Prevention (CDC) also recommends that people get both the COVID-19 and flu vaccines to stay safe. Citing a study it conducted on side effects after injecting two vaccines at the same time, the CDC pointed out that although injecting the COVID-19 booster and the flu vaccine at the same time will cause more side effects, the side effects are not as severe as just injecting the COVID-19 booster. People who receive both influenza and influenza vaccines are more likely to experience reactions such as fatigue, headache, and muscle aches than those who only receive the new coronavirus monovalent vaccine, but most of these reactions are mild and disappear quickly.”
Fubitai XBB vaccine will arrive in Hong Kong early next month, urging high-risk people to get vaccinated
Currently, the Omicron XBB lineage mutant virus strain is mainly prevalent in Hong Kong. Xu Shuchang, chairman of the Scientific Committee on New Discoveries and Animal Infectious Diseases, told this newspaper on the 18th that according to his understanding, the Fubitai XBB vaccine will arrive in Hong Kong early next month. The application for the Moderna XBB vaccine was submitted late and the authorities are still reviewing it for approval. Kong Fanyi, a member of the Scientific Committee on Vaccine Preventable Diseases and director and clinical professor of the Department of Infectious Diseases, Department of Medicine, Faculty of Medicine, HKU, predicts that Hong Kong will enter the peak period of the new crown epidemic next month and recommends that the elderly and high-risk individuals receive the XBB vaccine. (Editor’s note: In addition, a recent US study found that the level of antibodies produced by injecting the COVID-19 vaccine booster and the influenza vaccine at the same time was higher than that of inoculating the two vaccines separately.)
A government spokesperson responded to inquiries on the 18th and stated that the XBB vaccine had been approved for registration in Hong Kong at the beginning of this month (7th), and the vaccine was expected to arrive in Hong Kong within a short period of time. After checking the information, it was found that the vaccine approved for registration was Fubitai XBB.1.5 vaccine, and the certificate holder was Fosun Pharma.

Kong Fanyi predicts that the peak period of the new crown epidemic in December will be related to the outbreak of influenza “Plum Blossom Bamboo”
A government spokesman also reminded that citizens in high-risk groups should receive the COVID-19 vaccine as early as possible before the possible winter peak and should not wait for the XBB vaccine. A government spokesman said that priority will be given to those at higher risk, such as the elderly in institutions, to receive the first batch of vaccines. Details will be announced later.
Kong Fanyi said on the 18th that the new coronavirus and influenza are expected to break out “between plum blossoms and bamboos”. The peak period of the new coronavirus will be next month, and the winter flu peak will be after the Lunar New Year. It is expected to last for two or three months. However, it is estimated that there are many people at the beginning of the year. If you are infected with the flu and have certain antibodies, I believe that winter flu outbreaks will not be as severe as before.
Lin Yonghe, a member of the Scientific Committee on Vaccine Preventable Diseases, said that the increase in the number of people vaccinated against COVID-19 starting last month may be related to earlier reports that a COVID-19 outbreak may begin this month. His clinic provides Sinovac COVID-19 vaccine and influenza vaccine. Recently, about Between 5 and 10 people received both vaccines at the same time.
Increased cases of hand, foot and mouth disease may cause severe blisters on hands and feet of eczema patients
In addition, Guan Rihua, honorary clinical associate professor of the Department of Pediatrics and Adolescence of the University of Hong Kong, said on the commercial station’s “Political and Economic Saturday” on the 18th that the number of influenza B cases has increased in the past two weeks. He believes that influenza B may break out in Hong Kong in the future and calls for vaccination as soon as possible.
Kwan also said that there are still many children in frontline wards infected with various viruses, including hand, foot and mouth disease. Hong Kong is consistent with the global trend. This year’s outbreak of hand, foot and mouth virus is mainly of the A6 serotype, which can cause skin problems, and those with eczema are more affected. , the blisters on the hands and feet will be more serious, and when severe, they may ulcerate until the skin is completely gone. Guan said that children or adults can be infected, and the blisters will last for about a month. There is currently no vaccine for hand, foot and mouth disease against the A6 serotype. He called on the public to practice good personal hygiene, avoid contact with patient secretions, and not go to work or school after infection.
