Abstract:
The SARS-CoV-2 pandemic, which continues to this day, has been contained through a
number of measures. Vaccination plays a central role in the coping strategy. Vaccination
side effects are often mild to moderate, but rarely life threatening. Discussion and concern
about this is often a driving factor for reluctance to vaccinate in the population and should
therefore be continuously monitored and optimized when possible. Heterologous
administration in primary immunization appears to be superior to homologous in terms
of humoral immune response and vaccine efficacy over time.
The use of analgesics perivaccinarily seems to have a negative impact on vaccine efficacy
depending on the time period under consideration, despite marginally improved immune
response. A dedicated study for this issue should be performed outside a highly dynamic
pandemic event.
Arterial hypertension may be a protective factor in the infection event, albeit associated
with marginally lower antibody levels. Thus, the importance of measurable antibody
levels should be considered critically and only partially measures vaccination success.
Antibody quality should also be considered.
Our data show that some dsitinct vaccine side effects have a significant positive impact
on the humoral immune response, thus demonstrating in a limited way the relationship
between reactogenicity and immunogenicity. At the same time, however, the expression
of certain vaccine side effects may represent a negative predictive factor with respect to
vaccine efficacy.
Ultimately, the role of higher antibody levels in long-term vaccination success remains
questionable.
