At present, the vaccination rate of the new coronavirus among the elderly population in some parts of my country is still relatively low, and the risk of severe illness and death once infected is high.

  Recently, the Chinese Center for Disease Control and Prevention released the "New Crown Vaccination Science Questions and Answers for the Elderly", suggesting that the elderly who have not been vaccinated or have not received the "booster shot" should take the initiative to vaccinate as soon as possible if there is no absolute contraindication to the vaccine.

  Vaccine risk in older adults is rare

  The highest risk of severe illness in the whole population

  Elderly people who are vaccinated but are not willing to be vaccinated have two major concerns.

  First of all, some elderly people believe that if they stay at home or live in remote areas for a long time, they rarely go out or travel to other places, and the risk of infection is very small, so they do not need to be vaccinated.

China CDC pointed out that this kind of thinking is wrong.

Because modern society is developing rapidly, with more convenient transportation and more frequent flow of people, no place is a place that is isolated from the virus.

Currently, the mutated virus imported from some areas is highly contagious, and some cases have atypical clinical manifestations or even asymptomatic infections. Even if the elderly do not go out at home or live in remote rural areas, they may still be infected with the virus.

Especially if other people in the family work and study outside, and have more opportunities to come into contact with other people, it is possible to bring the virus home and cause the elderly to be infected.

Therefore, in order to avoid life-threatening threats to the elderly and a heavy burden to the family and society, the elderly should also "accompany everything" as soon as possible to protect themselves and others.

  Second, many elderly people still have concerns about vaccination. They are worried that they will be more prone to adverse reactions after vaccination when they are older and weaker.

China CDC stated that my country is currently conducting ongoing monitoring of abnormal reactions to suspected vaccination against the new coronavirus vaccine. The overall reported incidence of adverse reactions to the new coronavirus vaccine among the elderly population aged 60 and above is slightly lower than that reported by people under the age of 60. General reactions, a small number of people are abnormal reactions, and the reported incidence of serious abnormal reactions is less than one in a million, suggesting that the risk of vaccination may be very low.

  However, the risk of severe illness, especially death, of the elderly if infected with the new coronavirus is the highest among the entire population.

If the number of people who need to be hospitalized and treated increases, the medical system will be overloaded.

Therefore, in the face of the risk of the new coronavirus epidemic, the potential rare risks of vaccination, compared with the effective protection of vaccination in the elderly, and the benefits of reducing the pressure on the social medical service system, the elderly, especially the elderly, with Elderly people with underlying diseases need to actively seek protection from vaccines.

  How to get the vaccine?

  Homologous boosting or sequential boosting can be used

  The currently popular new coronavirus Omicron variant is highly infectious and occult. It has been observed that after the basic immunization of the existing vaccine is completed, the cross-protection of the Omicron variant has decreased.

All things considered, the best way to protect the elderly from the threat of COVID-19 is to be vaccinated, vaccinated throughout the course, and boosted in time.

  It is recommended that the elderly who have not been vaccinated be vaccinated as soon as possible, and those who have not been fully vaccinated should make up for the unvaccinated vaccine as soon as possible, including booster vaccinations.

At present, the state recommends two strategies for boosting immunization. One is homologous booster vaccination, that is, the booster vaccination is completed with the same technical route used for the original basic immunization; the other is sequential immunization booster vaccination, which is the same as the original basic immunization Vaccines with different vaccine technical routes are used to complete booster vaccinations.

Either one can effectively reduce the risk of severe illness and death. The elderly can complete booster immunization as soon as possible according to the local vaccine supply.

  In addition, the elderly are one of the priority groups for Covid-19 vaccination.

In terms of age, the current new crown virus vaccine only requires a lower age limit, but there is no upper age limit.

  There are four types of contraindications to the new crown vaccine

  The elderly over 60 years old can be vaccinated against the new coronavirus as long as they have no contraindications and are not the objects of delayed vaccination.

Those who cannot be vaccinated or cannot be vaccinated immediately are mainly in the following situations: those who are allergic to the active ingredients of the new coronavirus vaccine, any inactive ingredients, or substances used in the production process, or those who have been allergic to similar vaccines in the past; Those who have had severe allergic reactions to vaccines; those who have uncontrolled epilepsy and other serious neurological diseases; those who are febrile, or who have acute illnesses, or acute exacerbations of chronic diseases, or patients with uncontrolled severe chronic diseases.

  What needs special attention is that the elderly must be vaccinated against the new crown during the stable period of the disease. If they are not sure, they should consult a doctor; if the underlying disease is in an unstable state, the vaccination should be postponed until the state is stable. inoculation.

  Do not rely on vaccines for latent diseases

  Some diseases can delay vaccination

  Coincidence (coupling reaction) means that during the vaccination process, the vaccinee is in the incubation period of a disease or the early stage of the disease, and the disease occurs coincidentally after vaccination.

Therefore, the coincidence (coupling reaction) is not caused by vaccination, but overlaps in the time of occurrence, but in fact the occurrence of the coincidence has nothing to do with vaccination, nor is it an adverse reaction after vaccination.

  Second, to understand why the elderly co-morbidity is relatively high.

Because, as the elderly grow older, compared with adults and adolescents, the body is more likely to have some health problems, such as some with chronic underlying diseases, some with recurrence of chronic diseases, and some due to certain The incubation period of the disease increases the risk of illness, etc.

  Finally, it should be emphasized that some co-morbidities can be avoided by taking some measures to delay vaccination, but it is very difficult to completely avoid them.

The objects for deferred vaccination may include patients with fever, patients with uncontrolled epilepsy, acute exacerbation of chronic diseases, etc. The new coronavirus vaccine can be considered in time after the symptoms disappear or the acute exacerbation period of chronic diseases has passed.
