A vaccine that is generally recommended may be medically inappropriate for a small number of people due to severe allergies or a damaged immune system. In addition, a vaccine against a given disease may not be recommended for general use in a given country, or may be recommended only to certain populations, such as young children or older adults.
Fever, cough, runny nose, red Fever, cough, runny nose, inflamed eyes, rash. Typically, clinical diagnosis begins with the onset of fever and malaise about 10 days after exposure to the measles virus, followed by the emergence of cough, coryza, and conjunctivitis that worsen in severity over 4 days of appearing.
Viral disease. A viral disease (or viral infection) occurs when an organism's body is invaded by pathogenic viruses, and infectious virus particles (virions) attach to and enter susceptible cells. [1] Examples are the common cold, gastroenteritis and pneumonia. [2]
The World Health Organization (WHO) initiated the Expanded Program on Immunization (EPI) in May 1974 with the objective to vaccinate children throughout the world. Ten years later, in 1984, the WHO established a standardized vaccination schedule for the EPI vaccines: Bacillus Calmette-Guérin (BCG), diphtheria-tetanus-pertussis (DTP), oral ...
Rotaviruses are the most common cause of diarrhoeal disease among infants and young children. [1] Nearly every child in the world is infected with a rotavirus at least once by the age of five. [2] Immunity develops with each infection, so subsequent infections are less severe. Adults are rarely affected. [3]
The association between severe childhood infections and subsequent respiratory issues is not fully understood, particularly the suggested link between bronchiolitis, recurrent infantile wheeze, and childhood asthma. Unlike other vaccine-preventable respiratory pathogens, RSV has proven challenging for vaccine development.
Both vaccines are chemically inactivated whole virus vaccines for COVID-19. On 15 October, the Beijing Institute of Biological Products published results of its Phase I (192 adults) and Phase II (448 adults) clinical studies for the BIBP vaccine, showing it to be safe and well-tolerated at all tested doses in two age groups.
The thrombosis events associated with the COVID‑19 vaccine may occur 4–28 days after its administration and mainly affects women under 55. Several relatively unusual types of thrombosis were specifically reported to be occurring in those with the reaction: cerebral venous sinus thrombosis and thrombosis of the splanchnic veins.
