Abstract

Insights

Herpes zoster reactivation occurred in three healthy patients within two weeks of receiving the mRNA COVID-19 vaccine. Further investigation is needed to determine if herpes zoster is a side effect of mRNA SARS-CoV-2 vaccination.

Area of Science:

  • Neurology
  • Immunology
  • Infectious Diseases

Background:

  • The novel COVID-19 virus (SARS-CoV-2) prompted rapid development of mRNA vaccines.
  • Herpes zoster, a viral infection caused by the varicella-zoster virus, can reactivate under certain conditions.

Observation:

  • Three otherwise healthy patients developed herpes zoster reactivation shortly after receiving the Pfizer/BioNTech mRNA COVID-19 vaccine.
  • Presentations included herpes zoster meningitis, herpes zoster ophthalmicus involving the cornea, and herpes zoster affecting the eyelid.

Findings:

  • All three cases presented within two weeks of vaccination.
  • The neurological and ophthalmological manifestations suggest a potential link between mRNA vaccination and herpes zoster reactivation.

Implications:

  • Herpes zoster reactivation may be an infrequent side effect of mRNA SARS-CoV-2 vaccination.
  • Clinicians should consider herpes zoster in patients presenting with suggestive symptoms post-vaccination.
  • Further research is warranted to establish causality and understand the mechanisms involved.

Immunological Memory

Immunological memory, a pivotal pillar of the adaptive immune system, is responsible for the body's ability to remember and respond more swiftly and effectively to previously encountered pathogens. This remarkable feature is what makes vaccines so effective in preventing diseases.
What is Immunological Memory?
Immunological memory is an integral function of the immune system that allows it to recognize and react more rapidly and effectively to pathogens previously encountered. This feature...

Rous Sarcoma Virus (RSV) and Cancer

Rous Sarcoma virus or RSV was discovered by F. Peyton Rous in the year 1911 as a filterable transmissible agent that could cause tumors in chickens. He won a Nobel Prize for this discovery in 1966. His experiments clearly demonstrated that some cancers could be caused by infectious agents and led to the discovery of many more cancer-causing viruses in animals as well as humans.
RSV is a retrovirus that contains two copies of a plus-strand  RNA genome. Its genome consists of four main open...

Cancer Vaccines

Cancer treatment vaccines are a rapidly evolving field that offers a promising approach to immunotherapy. Unlike traditional vaccines that prevent diseases, cancer treatment vaccines are designed to treat existing cancers by stimulating the immune system to recognize and attack cancer cells.
Cancer vaccines come in two categories: preventive (prophylactic) and treatment (active). Preventive vaccines, such as the Human Papillomavirus (HPV) vaccine, protect against viruses that cause certain...

Viral Recombination00:57

Viral Recombination

Cells are sometimes infected by more than one virus at once. When two viruses disassemble to expose their genomes for replication in the same cell, similar regions of their genomes can pair together and exchange sequences in a process called recombination. Alternatively, viruses with segmented genomes can swap segments in a process called reassortment.
