Revaccination could help restore the child's immunity, the researchers said.

With little fuss, the majority of the 15-member committee voted both to recommend Shingrix and revaccination with it.
|
|
So this revaccination provides a partial answer, but it usually is not good enough to abruptly end the outbreak.

|
The new study recommends a third dosage of the vaccine to be applied at age 18, and suggests that clinical trials begin to study the effectiveness of revaccination.
|
|
However, if vaccines start losing effectiveness after the first year, as Dr. Wooten says, then constant revaccination would be required, since the immunity offered is only temporary for most vaccines.

ACIP members also recommended that Shingrix should be given routinely to Americans aged over 50 years, compared with 60 years for Zostavax, and they supported revaccination of people who previously received Zostavax.

|
Revaccination at periodic intervals is also indicated for those with other conditions such as asplenia or nephrotic syndrome.

Although the World Health Organization (WHO) endorses a singular dose of BCG, revaccination with BCG has been standardized in most, but not all countries. However, improved efficacy of multiple dosages has yet to be demonstrated.

For some countries, the cholera vaccine may be required despite the fact that the World Health Organization does not state this in their regulations. To avoid being quarantined or denied entry, check the entry requirements for the country by contacting the embassy or consulate, especially if there is a current cholera outbreak. Because it is not a universally required vaccination, one may need a separate cholera certificate or a physician's signed statement saying that the vaccine is contraindicated for certain health conditions. On the Yellow Card, the International Certificate of Vaccination or Revaccination Against Yellow Fever (Certificat International de Vaccination ou de Revaccination Contre la Fièvre Jaune) is located on the first two pages (in the original WHO version, 3rd and 4th pages) inside of the card.

Revaccination is not generally required. Annual screening is typically recommended. In 2001, Australia introduced a national Q fever vaccination program for people working in “at risk” occupations. Vaccinated or previously exposed people may have their status recorded on the Australian Q Fever Register, which may be a condition of employment in the meat processing industry or in veterinary research.

An International Certificate of Vaccination required to prove that someone has been vaccinated against yellow fever Soviet International Certificate of Vaccination or Revaccination Against Yellow Fever. The Carte Jaune or Yellow Card is an international certificate of vaccination (ICV). It is issued by the World Health Organization. It is recognised internationally and may be required for entry to certain countries where there are increased health risks for travellers.

The antibodies induced by vaccinia vaccine are cross- protective for other orthopoxviruses, such as monkeypox, cowpox, and variola (smallpox) viruses. Neutralizing antibodies are detectable 10 days after first-time vaccination, and seven days after revaccination. Historically, the vaccine has been effective in preventing smallpox infection in 95 percent of those vaccinated. Smallpox vaccination provides a high level of immunity for three to five years and decreasing immunity thereafter.

Mumdžić's brother developed a smallpox rash on March 20, resulting in medical authorities realizing that Mumdžić had died of smallpox. The authorities undertook massive revaccination of the population, helped by the World Health Organization (WHO), "almost the entire Yugoslavian population of 18 million people was vaccinated". Leading experts on smallpox were flown in to help, including Donald Henderson and Don Francis. By mid-May, the outbreak was contained and the country returned to normal life.

The current guidelines of the American College of Physicians call for the administration of the immunization between ages two and 65 when indicated, or at age 65. If someone received the immunization before age 60, the guidelines call for one-time revaccination. Majority of pharmacists indicate that they recommend all adults 65 and older receive a pneumococcal vaccination. They are generally educated on ACIP/CDC recommendations and believe that all people, regardless of age, should also be caught up on them.

Massachusetts was one of only 11 states that had compulsory vaccination laws. Massachusetts law empowered the board of health of individual cities and towns to enforce mandatory, free vaccinations for adults over the age of 21 if the municipality determined it was necessary for the public health or safety of the community. Adults who refused were subject to a $5 monetary fine. In 1902, faced with an outbreak of smallpox, the Board of Health of the city of Cambridge, Massachusetts adopted a regulation ordering the vaccination or revaccination of all its inhabitants.

The ViPS vaccine is given via injection, while the Ty21a is taken through capsules. Only people 2 years or older are recommended to be vaccinated with the ViPS vaccine, and it requires a revaccination after 2–3 years with a 55–72% vaccine efficacy. The alternative Ty21a vaccine is recommended for people 5 years or older, and has a 5-7-year duration with a 51–67% vaccine efficacy. The two different vaccines have been proven as a safe and effective treatment for epidemic disease control in multiple regions.

The reasons that the PEPAT invoked to remove Argentine Polar Dogs from Antarctica came from a conclusion of Scientific Committee on Antarctic Research, which reported that the dogs allegedly transmitted Canine distemper to seals, preyed on penguins, and they harbored parasites in their fur that were capable of upsetting the ecological balance of Antarctica. However, it has been proven that canine distemper is a virus, that can not be transmitted between species. The immunization records of the Argentine Antarctic bases where the Argentine Polar Dogs were raised and maintained show that all specimens were vaccinated as required by law, with two doses to the puppy and an annual reinforcement for all adults, including the annual revaccination for pregnant females that prevents infection. Expeditions without a permanent bases were obliged to follow this plan as well.
