Revaccinate

To administer a second or subsequent dose of a vaccine to a person or animal who has previously been vaccinated. This process is often necessary to boost immunity, especially against diseases where vaccine-induced protection wanes over time. Revaccination can involve the same vaccine used initially or a modified version, and is crucial for maintaining public health and protecting vulnerable populations. The timing and necessity of revaccination depend on factors like the specific vaccine, the individual's immune response, and the prevalence of the targeted disease.

Revaccinate meaning with examples

• After a measles outbreak, public health officials urged all adults to revaccinate if they had not received a booster shot in recent years. This helped create a wider 'herd immunity' effect, reducing the risk of further spread. Children were checked to see if they were in need of a booster and new vaccination records. The process can also be more simple than an initial vaccination.
• The veterinarian recommended **revaccinating** the dog annually against rabies, because the initial vaccine's efficacy might be reduced by the annual checkup of other vaccines. The owner followed this suggestion to keep her pet safe. Some vaccines provide protection for a few months, while other vaccines are more effective for many years, thus the importance of maintaining up to date records.
• Due to changing recommendations and an increasing threat of polio, the government is offering incentives for elderly citizens to revaccinate. They hope to raise the immunization rate to ensure the safety of the population. If an elderly citizen receives a new revaccination, they will maintain a record to keep them up to date to protect them from potential threats.
• Researchers are studying how often adults need to revaccinate against influenza to maximize protection against new strains. Some scientists are studying specific genes that can potentially help create the most effective vaccines. It's a constant process of adjusting recommendations based on evidence and real-world outcomes to make sure vaccines have their desired affect.
• A study in children showed a need to revaccinate against whooping cough every 5 years, as their immunity wanes more quickly than adults. This discovery prompted a change in pediatric vaccination schedules. The need to re-vaccinate helps to guarantee that immunity lasts throughout childhood, especially for diseases like whooping cough and chicken pox.
