Schematic diagram of a Parvoviridae virion A diagram of the canine parvovirus's capsid, containing 60 monomers of the capsid protein. Parvovirus virions are 23–28 nanometers (nm) in diameter and consist of the genome enclosed inside a capsid that is icosahedral in shape with a rugged surface. The capsid is composed of 60 structurally ...
As of 2020, no approved human vaccine existed against parvovirus B19. [54] Bernstein et. al. [35] tested in 2011 a possible candidate vaccine that was produced in insect cells. For the vaccine VP2/VP1 VLPs (virus-like particle) were used. This vaccine was approved to the I clinical phase, but was stopped due to unexplained reactions in patients.
According to the U.S. Centers for Disease Control and Prevention, while "any vaccine can cause side effects", [11] most side effects are minor, primarily including sore arms or a mild fever. [11] Unlike most medical interventions vaccines are given to healthy people, where the risk of side effects is not as easily outweighed by the benefit of ...
RSV vaccine side effects in older adults . The CDC lists the following as possible side effects of the RSV vaccine: Pain, redness, and swelling where the shot is given. Fatigue. Fever. Headache ...
Parvovirus B19 can also spread through blood or blood products, though infection through transfusion is rare. In addition, pregnant people who are infected can spread the virus to their unborn child.
However, parvovirus B19 only infects erythroid cells, so it is now part of the Erythrovirus genus. One well-known Parvovirus includes Canine parvovirus, which is known to infect dogs and cause inflammation of the small intestine and heart muscle. [65] [66] While all of these viruses are known to cause diseases, only parvovirus infects humans. [64]
Thanks to the development of vaccines, vaccinated dogs today are much better protected from CPV; dog owners are likely familiar with their pet's routine "parvo" shots at the veterinarian's office.
In reference to the negative-sense strand, the 3′-end is the left side and the 5′-end is the right side. [ 4 ] [ 5 ] Parvoviruses replicate their genomes through a process called rolling hairpin replication (RHR), which is a unidirectional, strand displacement form of DNA replication.
