Can Neutralizing Antibodies Provide Long-lasting Immunity?
The duration of immunity provided by neutralizing antibodies can vary. For some diseases, such as measles, neutralizing antibodies can confer lifelong immunity after infection or vaccination. In contrast, for others like influenza, the virus rapidly mutates, necessitating annual vaccinations to maintain immunity. SARS-CoV-2 has also shown some degree of mutation, raising questions about the long-term efficacy of neutralizing antibodies generated by current vaccines.
