After receiving the pneumonia vaccine, the body generates an immune response that produces antibodies. Typically, these antibodies provide lifelong immunity. Patients with weak constitutions might need a booster shot every 3-5 years after vaccination, which generally can also lead to lifelong immunity.

Vaccinations should be administered at local, formal medical institutions. One can visit the local centers for disease control and prevention to get vaccinated. During the vaccination period, if there are any adverse reactions, they should be addressed promptly. After receiving the vaccine, it is advisable to remain at the medical facility for half an hour for observation before leaving, to prevent the occurrence of adverse reactions.
