Influenza, COVID-19, tetanus, pertussis and hepatitis B pose increased risk for pregnant women and infants and could be mitigated by maternal immunization. In India Tetanus-diphtheria (Td) and COVID-19 vaccines are recommended during pregnancy, while influenza and tetanus-acellular pertussis-diphtheria (Tdap) vaccines are not. We conducted a multicenter study from November 2021 to June 2022 among pregnant women ( = 172) attending antenatal clinics in three public hospitals in West Bengal, to understand the factors that influence women's decisions to get vaccinated during pregnancy. Questions assessed vaccination coverage, knowledge, intention and willingness to pay for influenza vaccine, and factors influencing decisions to get Td, influenza, and COVID-19 vaccines. 152/172 (88.4%) women were vaccinated with Td, 159/172 (93%) with COVID-19, 1/172 (0.6%) with influenza, and none with Tdap. 10/168 (6%) had received hepatitis B vaccine (HBV). Community health workers advice was crucial for Td uptake and, the belief of protection from COVID for COVID-19 vaccines. Most women were unaware about Tdap (96%), influenza (75%), and influenza severity during pregnancy and infancy (85%). None were advised for influenza vaccination by healthcare providers (HCP), albeit, 93% expressed willingness to take, and pay INR 100-300 (95% CI: ≤100 to 300-500) [$ 1.3-4.0 (95% CI: ≤1.3, 4-6.7)] for it. Vaccination on flexible dates and time, HCP's recommendation, proximity to vaccination center, and husband's support were most important for their vaccination decisions. Women were generally vaccine acceptors and had high uptake of vaccines included in the Universal Immunization Program (UIP). Inclusion of influenza, Tdap, and HBV into UIP may improve maternal vaccine uptake.
