The last week of April every year
World Immunization Week
Today we call on the elderly
Vaccination and booster vaccines
At 10:00 on April 26, Shanghai held a press conference on the prevention and control of the new crown pneumonia epidemic, at which it was reported that on April 25, there were 52 new local deaths. The average age is 83.1 years, the minimum age is 33 years, and the maximum age is 100 years. The 33-year-old patient, a male, died of sudden cardiac arrest due to sudden cardiac arrest and ineffective rescue, and was diagnosed with sudden cardiac death, and had received 2 doses of COVID-19 vaccine. The other 51 patients were all present with multi-organ underlying diseases, including advanced liver cancer, chronic obstructive pulmonary disease, acute coronary syndrome, severe hypertension, diabetes, sequelae of cerebral infarction, Parkinson's disease, Alzheimer's disease (commonly known as Alzheimer's disease), uremia and other serious diseases of important organs. The causes of death are all underlying diseases.
Such elderly people
The risk is higher
In addition, on 21 April 2022, the report analysis of 8,973 deaths from the fifth wave of the new crown epidemic (Omicron outbreak) in Hong Kong showed that more than 95% of the deaths in Hong Kong are elderly, and the case fatality rate of unvaccinated elderly people is still extremely high, as follows:
It can be seen from the table that the case fatality rate of fully vaccinated and intensively vaccinated people is significantly lower than that of unvaccinated people. In addition, stepping up vaccination can further reduce case fatality rates in older populations.
It can be seen that compared with young people, the elderly with weak immune function and often accompanied by a variety of underlying diseases have a higher risk of severe illness and death once infected with the new crown virus.
Secondly, COVID-19 vaccination is the most effective scientific intervention to interrupt the spread of the epidemic and reduce the case fatality rate, and strengthening vaccination will also help reduce the case fatality rate of the elderly population.
Called!
Get vaccinated against COVID-19
According to the Statistics of the National Health Commission, as of March 17, 2022, the vaccination status of people over the age of 60 in mainland China is as follows:
As can be seen from the table, the proportion of elderly people receiving booster vaccines in all age groups decreased significantly compared with the elderly population who received one dose and completed the full basic immunization. In short, there are fewer elderly people on the mainland who receive booster vaccines!
The number of people over the age of 60 in the mainland is 264 million, of which 211.76 million elderly people have completed the full vaccination, which means that 52 million elderly people over the age of 60 have not completed the full vaccination of the new crown vaccine.
Why are there calls for elderly vaccinations?
The immune function of the elderly is relatively weak, and the antibody level and protective effect produced by people over 60 years old after completing the basic immunization of the vaccine are relatively lower than those of people aged 15-59 years, and the proportion of severe /critical illness in the elderly once infection occurs is higher. Data from Hong Kong show that vaccination with enhanced vaccination can significantly reduce the case fatality rate. At the same time, existing studies have also shown that the risk of severe illness and death after the elderly are vaccinated with booster immunization can be reduced by more than 90%. It can be seen that it is very necessary for the elderly to receive vaccinations and booster injections.
At present, the mainland recommends two enhanced vaccination strategies, one is homologous intensive vaccination, that is, the same technical route used in the original basic immunization is used to complete the enhanced vaccination, and the other is sequential immunization enhancement vaccination, that is, the use of vaccines with different technical routes from the original basic immunization to complete the enhanced vaccination.
The classical theory of infectious diseases is to control the source of infection, cut off the transmission route, and protect susceptible people. One of the most effective means of protecting susceptible people is vaccination. According to the analysis of the incidence, severe illness and death of new crown pneumonia published by various countries, the elderly population over 60 years old is a high-risk group of severe illness and death. On the one hand, the elderly have a decline in their own immunity, and on the other hand, the proportion of chronic underlying diseases is high, so the best way to protect the elderly from the threat of new crown pneumonia is still to be vaccinated, so that the whole process of vaccination and timely vaccination and strengthen vaccination, and strive to achieve the goal of "full access".
Elderly vaccinations
What to watch out for?
ask
The elderly at home do not go out all year round, is it necessary to get the new crown virus vaccine?
answer
Necessary! The new crown virus is highly contagious and easy to spread, although the elderly do not leave their homes, but family, social workers and other surrounding groups may bring them the risk of infection; the elderly are at high risk of severe illness and death after infection with the new crown virus, and after vaccination, the risk of illness, severe illness and death can be effectively reduced. Therefore, for the elderly who rarely go out, if they are in good health and meet the conditions for vaccination, it is recommended to get the new crown virus vaccine.
ask
Is there a maximum age limit for COVID-19 vaccination?
answer
At present, the new crown virus vaccine has requirements for the lower age limit, and there is no provision for the upper limit of age, as long as it is more than 3 years old, the new crown virus vaccine can be vaccinated. Vaccination with the "booster needle" requires you to be at least 18 years old.
ask
What are the contraindications to THE NEW CROWN vaccine in the elderly and what do I need to pay attention to?
answer
Elderly people over the age of 60 can be vaccinated against the new crown virus as long as there are no contraindications and are not deferred vaccination subjects. The main conditions in which vaccination cannot be vaccinated or cannot be vaccinated immediately are as follows:
1. Those who are allergic to the active ingredient of the new coronavirus vaccine, any of the inactive ingredients, or substances used in the production process, or those who have been allergic when they have previously received the same vaccine;
2. Those who have had a severe allergic reaction to the vaccine in the past (such as acute allergic reaction, angioedema, dyspnea, etc.);
3. People with uncontrolled epilepsy and other serious neurological diseases (such as transverse myelitis, Guillain-Barré syndrome, demyelinating disease, etc.);
4. Patients with fever, or acute illness, or acute onset of chronic disease, or uncontrolled severe chronic disease.
5. Special reminder that the elderly must be in the stable period of the disease, they can not get it accurately, they should consult a doctor; if the underlying disease is in an unstable state, the vaccination should be suspended, and then go to the vaccination when the state is stable.
6. Some chronic underlying diseases, such as diabetes, hypertension, etc., some people may have frequent recurrence, if the physical state, health status is stable, it is possible to vaccinate, because these basic diseases of the population, often once infected easily become a severe new crown pneumonia population.
