GSK plc announced the launch of Vaccine Track, a comprehensive platform developed by GSK and IQVIA for use by public health officials, industry leaders and medical professionals to strengthen vaccination data transparency, raise awareness and publicly share vaccination trends to aid improvements in routine adult vaccinations to create healthier communities across the US. This resource will provide frequent and relevant data on trends to focus and enhance public health efforts. Collective experience throughout the COVID-19 pandemic has elevated the public's understanding of the value of vaccines and the importance of data in helping to prevent disease and death, especially in adult and older adult populations.

Vaccination rates for CDC-recommended vaccines were low before the pandemic and despite heightened awareness, adult immunization rates significantly declined during the pandemic, compounding already low rates. This is significant because even small drops in immunizations can lead to a resurgence of disease. The Vaccine Track platform will enable users to: Identify vaccination trends for adults 19+ in the US across multiple vaccines; Scan immunization claims data nationally and sub-nationally across years; Track trends based on 2019 pre-COVID-19 baseline vaccination uptake; Highlight where differences exist based on demographics (e.g., age, race/ethnicity, gender, payer type).

Vaccine Track data insights revealed sustained decline of recommended adult immunizations, excluding flu vaccinations, across the US during the pandemic. This was particularly true for minority populations, which already showed lower rates of immunization pre-pandemic. National trends for adults aged 19 and older continue to remain below pre-pandemic 2019 baselines with an average decrease of 18% through 2021 in overall claims for recommended vaccines, excluding influenza.

Vulnerable populations may be especially impacted by this trend; Average monthly overall claims data through 2021 for recommended vaccines (excluding influenza) were 12-42% below by payer compared to a 2019 baseline; For Medicare, analysis found more than 30% reduction in overall claims for recommended vaccines among Black and Hispanic populations between 2019 and 2021. This highlights the significant potential impact and exacerbation on disparities in immunization rates in Medicare due to the pandemic; At the state level, as of December 2021 nearly half of the states in the US were facing greater than 30% reductions in overall claims for recommended vaccines from 2019 pre-pandemic levels.
