Adverse events4
- The most common severe adverse events related to BCG vaccination are nonsuppurative and suppurative lymphadenitis. (cdc.gov)
- Although treatment was at the discretion of clinicians, national TB program treatment guidelines did not include management of BCG-related adverse events. (cdc.gov)
- No BCG-related systemic adverse events occurred. (healthtipsgalaxy.com)
- The Hexa vaccine caused fewer adverse events compared with the pentavalent vaccine, probably due to the acellular pertussis component - 0.8 versus 1.5 per 100 000 doses administered respectively. (who.int)
Doses3
- An Indian child is ill fated to receive about 20 to 25 different primary or booster doses of vaccines within its first five years of life. (hpathy.com)
- This data set is unique and exciting because the patients were all vaccinated with multiple doses of BCG prior to the onset of the epidemic. (healthtipsgalaxy.com)
- The most frequently reported AEFI were BCG adenitis and local reactions - 31.1 and 4.1 per 100 000 doses respectively. (who.int)
VPM10022
- The large-scale phase III priMe study will build on promising preliminary trials, in adults and children, of this updated version of BCG, known as VPM1002. (edctp.org)
- Furthermore, production methods for VPM1002 are relatively simple and straightforward to scale up, so the vaccine could meet global demand and overcome some of the supply difficulties recently experienced with BCG. (edctp.org)
Commonly2
- Bacillus Calmette-Guérin (BCG) vaccine is one of the most commonly used vaccines for tuberculosis (TB) worldwide ( 1 ). (cdc.gov)

Cohort2
- We examined this association of early life BCG vaccination and age at vaccination with type 1 diabetes incidence in adolescence in a large representative cohort in Quebec. (nih.gov)
- The cohort included 387,704 individuals born in Quebec between 1970 and 1974 whose BCG vaccination status was determined from a provincial registry. (nih.gov)
Primarily2
- Bacillus Calmette-Guérin ( BCG ) vaccine is a vaccine primarily used against tuberculosis (TB). (wikipedia.org)
- The Bacillus Calmette-Guerin (BCG) vaccine, primarily developed to prevent tuberculosis, is administered to over 130 million babies worldwide each year. (clinicallab.com)
19211
- The BCG vaccine was first used medically in 1921. (wikipedia.org)
Antigens1
- Hence, boosting BCG with latency associated antigens like α-crystallin may prove to be an effective strategy for controlling TB. (nature.com)
Type 1 diabet5
- The Bacillus Calmette-Guerin (BCG) vaccine could reduce the incidence of type 1 diabetes through non-specific immunomodulation. (nih.gov)
- Cox proportional hazards regression was used to estimate the association of BCG vaccination and age at vaccination with type 1 diabetes. (nih.gov)
- Our results suggest that BCG vaccination does not prevent type 1 diabetes in adolescence. (nih.gov)
- The researchers are hoping the results will spur a larger scale study of the effects of the BCG vaccine in patients with type 1 diabetes, considered among the most vulnerable groups to COVID-19. (healthtipsgalaxy.com)
- The 144 adult type diabetics (96 BGC treated and 48 placebo) analyzed in the COVID-19 trial were part of an ongoing Phase IIb clinical trial testing BCG as a treatment for adults with established type 1 diabetes. (healthtipsgalaxy.com)
