Older adults have lower rates of adverse reactions than younger adults
As of 24:00 on March 21, Guangzhou has received 52.247 million doses of the new coronavirus vaccine, 19.562 million people have been vaccinated throughout, and 12.219 million people have completed booster immunization.
Among them, a total of 4.387 million doses and 1.778 million people were vaccinated against people aged 60 and over, of which 1.609 million were vaccinated throughout the course of the disease and 1.003 million were boosted.
Guangzhou Daily News (all-media reporter Wu Ren, correspondent Sui CDC) Yesterday, experts from the Guangzhou Center for Disease Control and Prevention said that at this stage, attention should be paid to the vaccination of the elderly, and they once again clarified their concerns about the vaccination of the elderly against the new crown virus. .
Zhang Chunhuan, deputy director of the Immunization Planning Department of the Guangzhou Center for Disease Control and Prevention, introduced that the new coronavirus is a new virus, and the entire population is susceptible. Among them, the most vulnerable are the elderly with relatively low immune function, and the elderly often have underlying diseases and chronic diseases. , the risk of infection will be greater.
Data from some high-endemic areas overseas show that compared with young people aged 18 to 29, the risk of hospitalization for people aged 65 to 74 is increased by 4 times, and the risk of death is increased by 65 times; this risk continues to increase with age. Increase, to people over 85 years old, the risk of hospitalization increased by 12 times, and the risk of death increased by 340 times; in some areas, more than 90% of the infected people who died were elderly.
Zhang Chunhuan said that from the data, it can be seen that the effect of the new coronavirus vaccine in preventing severe illness and preventing death is very significant.
Experts dispel doubts
Can people with underlying diseases be vaccinated?
Under stable drug control, it is not considered a contraindication to vaccination
If the elderly have underlying diseases such as high blood pressure, high blood lipids, and diabetes, can they still be vaccinated against the new coronavirus?
"It is now clear that even if you have chronic diseases or underlying diseases, as long as you are not allergic to the components of the new coronavirus vaccine, or you have not experienced severe acute allergic reactions to other vaccines in the past, chronic diseases and underlying diseases are not in the acute attack stage, that is, Under the condition of stable drug control, it is not considered a contraindication to vaccination and can be vaccinated."
At present, more than 3 billion doses of the new coronavirus vaccine have been vaccinated across the country, and hundreds of millions of doses of the new coronavirus vaccine made in China have been vaccinated on the elderly worldwide.
"A large number of vaccination data show that after the elderly are vaccinated, the probability of adverse reactions is lower than that of young people, and it is mainly transient reactions such as fever and local reactions at the vaccination site. Therefore, the new coronavirus vaccine is not suitable for the elderly. It is also safe to speak." Zhang Chunhuan said.
At home all year round, is there little risk of infection?
Asymptomatic infection rate increases
"I'm at home all the year round, and I don't travel far. The risk of infection is not high. Is it necessary to get vaccinated?" Zhang Chunhuan reminded everyone to pay attention to this idea. The positive effect is that the proportion of asymptomatic infected persons increases among the infected persons. "Even if the elderly themselves do not travel far, it may happen that young people in the family are infected with the Omicron variant, but due to vaccination Vaccines have good immunity, so they have no symptoms and are asymptomatic infections, but when young people bring the virus home and infect the elderly who have not been vaccinated against the new coronavirus, the harm is much greater."
He added that due to the good prevention and control of the domestic epidemic, the vaccination strategy is to follow the high-risk groups and key groups, and finally gradually transition to the elderly over 60 years old.
Overseas, because of the high risk, it is started from the elderly and gradually vaccinated to younger age groups, which also confirms the necessity of vaccination for the elderly.
According to the immunization principle of vaccination, according to the calculation of the second dose 3 weeks after the first dose, it will take about 1.5 months for the antibody in the body to reach a better level at the earliest after the whole immunization.
Zhang Chunhuan appealed to the elderly not to wait until the epidemic is approaching to consider vaccination. As the elderly with relatively fragile health, they need to be vaccinated in time.
Elderly people who have been fully vaccinated should also receive booster vaccination half a year after the full vaccination, which can not only further improve the protection against hospitalization, severe illness and death, but also effectively reduce the breakthrough caused by the Omicron variant. risk of infection.
