Objectives: The World Health Organization pre-qualified single-dose typhoid conjugate vaccine (TCV) and requested data on co-administration with routine vaccines. The co-administration of Typbar TCV (Bharat Biotech International) with routine group A meningococcal conjugate vaccine (MCV-A) and measles–rubella (MR) vaccine was tested. Methods: This was a double-blind, randomized controlled trial performed in Ouagadougou, Burkina Faso. Children were recruited at the 15-month vaccination visit and were assigned randomly (1:1:1) to three groups. Group 1 children received TCV plus control vaccine (inactivated polio vaccine) and MCV-A 28 days later; group 2 children received TCV and MCV-A; group 3 children received MCV-A and control vaccine. Routine MR vaccine was administered to all participants. Safety was assessed at 0, 3, and 7 days after immunization, and unsolicited adverse events and serious adverse events were assessed for 28 days and 6 months after immunization, respectively. Results: A total of 150 children were recruited and vaccinated. Solicited symptoms were infrequent and similar for TCV and control recipients, as were adverse events (group 1, 61.2%; group 2, 64.0%; group 3, 68.6%) and serious adverse events (group 1, 2.0%; group 2, 8.0%; group 3, 5.9%). TCV generated robust immunity without interference with MCV-A vaccine. Conclusions: TCV can be safely co-administered at 15 months with MCV-A without interference. This novel study on the co-administration of TCV with MCV-A provides data to support large-scale uptake in sub-Saharan Africa.Keyword

Early smallpox vaccine manufacturing in the United States: Introduction of the "animal vaccine" in 1870, establishment of "vaccine farms", and the beginnings of the vaccine industryEsparza, J.; Lederman, S.; Nitsche, A. (Elsevier Ltd, 2020)For the first 80-90 years after Jenner's discovery of vaccination in 1796, the main strategy used to disseminate and maintain the smallpox vaccine was arm-to-arm vaccination, also known as Jennerian or humanized vaccination. A major advance occurred after 1860 with the development of what was known as "animal vaccine", which referred to growing vaccine material from serial propagation in calves before use in humans. The use of "animal vaccine" had several advantages over arm-to-arm vaccination: it would not transmit syphilis or other human diseases, it ensured a supply of vaccine even in the absence of the spontaneous occurrence of cases of cowpox or horsepox, and it allowed the production of large amounts of vaccine. The "animal vaccine" concept was introduced in the United States in 1870 by Henry Austin Martin. Very rapidly a number of "vaccine farms" were established in the U.S. and produced large quantities of "animal vaccine". These "vaccine farms" were mostly established by medical doctors who saw an opportunity to respond to an increasing demand of smallpox vaccine from individuals and from health authorities, and to make a profit. The "vaccine farms" evolved from producing only smallpox "animal vaccine" to manufacturing several other biologics, including diphtheria- and other antitoxins. Two major incidents of tetanus contamination happened in 1901, which led to the promulgation of the Biologics Control Act of 1902. The US Secretary of the Treasury issued licenses to produce and sell biologicals, mainly vaccines and antitoxins. Through several mergers and acquisitions, the initial biologics licensees eventually evolved into some of the current major American industrial vaccine companies. An important aspect that was never clarified was the source of the vaccine stocks used to manufacture the smallpox "animal vaccines". Most likely, different smallpox vaccine stocks were repeatedly introduced from Europe, resulting in polyclonal vaccines that are now recognized as "variants" more appropriately than "strains". Further, clonal analysis of modern "animal vaccines" indicate that they are probably derived from complex recombinational events between different strains of vaccinia and horsepox. Modern sequencing technologies are now been used by us to study old smallpox vaccine specimens in an effort to better understand the origin and evolution of the vaccines that were used to eradicate the smallpox.

Evaluation of a booster dose of pentavalent rotavirus vaccine coadministered with measles, yellow fever, and meningitis a Vaccines in 9-Month-old malian infantsTapia, Milagritos D.; Sow, Samba O.; Fitzpatrick, Meagan; Neuzil, Kathleen M.; Kotloff, Karen L. (Oxford University Press, 2018-07-13)Background Rotavirus vaccines given to infants are safe and efficacious. A booster dose of rotavirus vaccine could extend protection into the second year of life in low-resource countries. Methods We conducted an open-label, individual-randomized trial in Bamako, Mali. We assigned 600 infants aged 9-11 months to receive measles vaccine (MV), yellow fever vaccine (YFV), and meningococcal A conjugate vaccine (MenAV) with or without pentavalent rotavirus vaccine (PRV). We assessed the noninferiority (defined as a difference of ≤10%) of seroconversion and seroresponse rates to MV, YFV, and MenAV. We compared the seroresponse to PRV. Results Seroconversion to MV occurred in 255 of 261 PRV recipients (97.7%) and 246 of 252 control infants (97.6%; difference, 0.1% [95% confidence interval {CI}, -4.0%-4.2%]). Seroresponse to YFV occurred in 48.1% of PRV recipients (141 of 293), compared with 52.2% of controls (153 of 293; difference, -4.1% [95% CI, -12.2%-4.0%]). A 4-fold rise in meningococcus A bactericidal titer was observed in 273 of 292 PRV recipients (93.5%) and 276 of 293 controls (94.2%; difference, -0.7% [95% CI, -5.2%-3.8%]). Rises in geometric mean concentrations of immunoglobulin A and immunoglobulin G antibodies to rotavirus were higher among PRV recipients (118 [95% CI, 91-154] and 364 [95% CI, 294-450], respectively), compared with controls (68 [95% CI, 50-92] and 153 [95% CI, 114-207], respectively). Conclusions PRV did not interfere with MV and MenAV; this study could not rule out interference with YFV. PRV increased serum rotavirus antibody levels.
