Is rabies vaccination lifelong immunity, and is rabies vaccination valid for life after one shot?

The human diploid cell rabies vaccine is a lyophilized powder injection. Since 2004, China has been developing human diploid cell rabies vaccine, and in 2014, China's first lyophilized human rabies vaccine with independent intellectual property rights was launched. So is the rabies vaccine effective for life?

1. The rabies vaccine is only given once and cannot reach the level of lifelong effectiveness.

2. After the complete five shots of rabies vaccine, the corresponding antibody can only last for several years, for the sake of insurance, because this antibody will gradually decline over time, without the corresponding blood test, it is recommended that after the complete rabies vaccine is completely completed half a year later, bitten by a dog or other animal, the rabies vaccine should be boosted.

3. If it is more than three years, it should also be injected in the whole process. Therefore, even if the rabies vaccine is fully vaccinated with five shots, it cannot continue to be effective for life. However, in contrast, if you are bitten by a dog again after the rabies vaccination, you do not need to inject rabies serum or immunoglobulin again.

4. From this aspect, after the rabies vaccine has been given a full five shots, the corresponding effects can last for life. If the full five shots of the rabies vaccine are not completed, and only one shot is given, the antibodies have not been developed at this time, and it will not continue to be effective for life.

1 Not lifelong immunity.

Neither the rabies vaccine for rabies prevention after being bitten by a dog or other small animal, nor the rabies vaccine for rabies prevention in healthy people who have not been bitten in advance, is not lifelong immunity, and then needs to be injected again after being bitten or invalidated.

2 Because the rabies vaccine is an inactivated vaccine.

Rabies vaccine is a rabies-specific immunoglobulin-type inactivated vaccine, because the antibody is a protein, it will be metabolized and hydrolyzed in the human body over time.

3 general tube 6 months.

The rabies vaccine is valid for 6 months from the day the person is fully vaccinated, so even if you have been vaccinated before, if you are bitten again after the expiration date, you need to be re-vaccinated against rabies.

4. According to the following situations, it is solved

1. If the re-exposure occurs during the immunization process, the full course of vaccination will continue to be completed according to the original procedure, and there is no need to increase the dose;

2. After the full course of immunization, those who are re-exposed within half a year from the last dose generally do not need to be re-immunized;

3. Those who are re-exposed within half a year to 1 year after full immunization should receive 1 dose of vaccine on 0 and 3 days;

4. Those who are re-exposed within 1-3 years should receive 1 dose of vaccine every day;

5. Those who have been in high school for more than 3 years should be fully vaccinated.

Note: Even if you have been bitten again after being vaccinated against rabies, you should treat the wound promptly and thoroughly.

The rabies vaccine is generally only effective for six months after the last dose. If it is more than half a year, it needs to be re-injected.

It is not valid for life, but there is a term of protection.

The first full course of rabies vaccination, the effective protection period is half a year (absolute protection period is 3 months), and there is no need to re-expose the general degree of re-exposure (such as being scratched and bitten by dogs and cats, etc.) during the effective protection period.

People who have been beaten, the protection period has expired, and they are bitten by dogs, and they need to be strengthened immunization, and only 2 injections are needed to strengthen immunization, no protein is required, and the effective protection period is 1-3 years after strengthening immunization.

Personally, I don't think the rabies vaccine is effective for life. After a person is bitten by a dog, he is vaccinated against rabies and develops immunity; If you are bitten by a dog again, you have to get a rabies vaccine.

Is the rabies vaccine effective for life? Unlike other vaccines, the rabies vaccine is not immunized for life. After a full five-dose rabies vaccine, the corresponding antibodies remain positive for several years.

Half a year after the rabies vaccine is fully injected, if you are bitten by a dog again, you still need to be injected with rabies vaccine at this time. Rabies vaccine only needs to be boosted, and within one year and six months away, two booster shots are required; Re-exposure between 1-3 years requires a booster injection of three shots. Re-exposure after 3 years requires full rabies vaccination.

Therefore, the rabies vaccine is not lifelong immunity, and if you are bitten or scratched by an animal that may be infected with rabies for a long time after receiving the rabies vaccine, it is likely that you will need a booster injection or a full course of rabies vaccination.

Not for life.

There is also a time limit.

If you are bitten, you still need to be beaten.

No, you have to be beaten once you get caught or bitten once.

No, every time you get bitten, you have to fight.

Guiding Opinions: Article 21 of the Specifications for the Prevention and Treatment of Rabies Exposure (2009 Edition) Disposal after re-exposure.

Wound management: Wound management should be carried out first, promptly, and thoroughly after any exposure.

Vaccination: In general, antibody levels can be maintained for at least 1 year after full rabies vaccination. If re-exposure occurs during immunization, the full course of vaccination will continue to be completed according to the original procedure, and no additional dose is required; Those who are re-exposed within half a year after full immunization generally do not need to be re-immunized; Those who are re-exposed within six months to one year after full immunization should receive one dose of vaccine on day 0 and day 3; Those who are re-exposed within 1-3 years should receive 1 dose of vaccine per day; Those who have been vaccinated for more than 3 years should be fully vaccinated.

Not lifelong immunity.

After receiving rabies vaccine, the effective protection period is half a year, more than half a year, and then bitten by a dog, you need to re-inject the vaccine, but only need to take another 2 injections (the protection period can reach more than 1 year), and each time you strengthen it later, the actual protection period is longer.

Rabies has only one week from prodromal to death. Some people are scared to death when they have symptoms, and they are always worried about whether they are suffering from rabies attacks, which is unnecessary, because there are no symptoms during the incubation period, and the onset period is only 3-4 days from the appearance of symptoms to three fears, and only 1 week to death, so if a person feels unwell for several days, it can still be on, then it is not rabies at all.

Not necessarily, play a few more times.
