Be cautious when going abroad to get the cervical cancer vaccine. Going abroad to get the cervical cancer vaccine is not suitable for everyone

The "Guidelines for Cancer Screening, Early Diagnosis and Early Treatment in China" pointed out that in the near future, cervical cancer will be the first malignant tumor that humans can fully prevent and eradicate through immunization. This credit should be remembered by the "cervical cancer vaccine". At present, cervical cancer vaccines are still not available in 124 countries and regions around the world, including Hong Kong, China. In recent years, many people have traveled to Hong Kong and other places to get cervical cancer vaccines. The reporter interviewed Cheng Xiaodong, director of the Medical Education Department and chief physician of the Obstetrics and Gynecology Hospital Affiliated to Zhejiang University School of Medicine, and learned that going abroad to get cervical cancer vaccines is not suitable for everyone. It is difficult to preserve and it is not recommended to bring it back for vaccination. The Obstetrics and Gynecology Hospital Affiliated to Zhejiang University School of Medicine is one of the four hospitals participating in the "Basic Clinical Trial of Cervical Cancer Vaccine Safety and Effectiveness" project of the State Food and Drug Administration. Cheng Xiaodong pointed out that the official name of "cervical cancer vaccine" is human papillomavirus (hereinafter referred to as HPV) vaccine. HPV infection is the cause of cervical cancer. Intercepting the source of infection can effectively prevent the disease. "At present, we are still further observing and understanding the long-term effects of the vaccine. It is not clear when it will be available in China." Cheng Xiaodong introduced. There is no information about the launch of vaccines in the mainland, so some anxious women made a special trip to Hong Kong for vaccination. The reporter did some calculations: vaccination at regular hospitals and clinics in Hong Kong at their own expense costs about RMB 1,000-1,200 per shot. Imported vaccines need to be injected three times within 6 months. If you go from the mainland, including round-trip air tickets, accommodation fees, etc., it is estimated that the cost of completing all injections will be around 15,100 yuan. Some women think the cost is high, or because the processing of Hong Kong and Macau Passes is strict, the client buys it from Hong Kong and gets it in the mainland; some people get one shot in Hong Kong and take the remaining two shots back to find someone to help. Cheng Xiaodong said that it is safe for women to get vaccinated in regular, government-regulated medical institutions in Hong Kong. But it is not recommended to bring the medicine back to the mainland for vaccination. "Since HPV vaccines have corresponding strict requirements for transportation and storage. Professional institutions need to strictly control each link when transporting vaccines and control the temperature throughout the process. It is difficult for individuals to preserve drugs, which can easily lead to the deterioration of vaccines. From affecting the effect to unpredictable reactions." Be prepared before the injection If you want to go to Hong Kong for vaccination, it is best to do cervical smears and HPV screening in the mainland for reference by Hong Kong doctors; and make an appointment for vaccination by phone. The most important thing is to plan the time for 3 vaccinations. After each vaccination, it is best to stay in Hong Kong for one more day so that you can see a doctor in time when adverse reactions occur. People with colds and fevers, those who are allergic to vaccine ingredients and pregnant women should not receive this type of vaccine. And after vaccination, do not get pregnant within half a year. If you get pregnant after the injection starts, you should wait until after delivery to continue the injection. Early vaccination, good effect Although the vaccine is very good, it is impossible to vaccinate once and for all. Research conducted by the Chinese Center for Disease Control and Prevention and Peking University First Hospital shows that vaccination can prevent most cervical cancers, but it cannot play a 100% protective role. If you have already been infected with the vaccine HPV type, re-vaccination is equivalent to "closing the fold after the sheep have been sheep", which is of limited significance. The World Health Organization believes that the age of people who are vaccinated is 9-26 years old; the most suitable age for vaccination is 11-12 years old, or before having sex. "The age of vaccination should be considered according to national conditions. The United States requires vaccination at the age of 9 because teenagers in this country start having sex earlier. Even if there is sex, it is not necessarily completely ineffective. As long as there is no infection of the type of vaccine, vaccination is beneficial." Cheng Xiaodong said. "Just like people have to walk on two legs, vaccination is one of them, and the other is regular screening." Cheng Xiaodong emphasized that European and American countries require women to continue regular screening after vaccination, and the screening mode and frequency are the same as those who have not been vaccinated. "All women who have had sex should have regular physical examinations. Early marriage, many children, frequent sex or cervical infection need to undergo cervical cancer screening once a year to truly prevent it before it happens."
