By Aaron Pitkin

Each month, CREATION.co’s COVID-19 vaccine tracker brings you the latest insights into the online healthcare professionals (HCPs) responding to the latest news and trial results for COVID-19 vaccine candidates.

Discover what healthcare professionals (HCPs) think about pharmaceutical products and their manufacturers, as it happens, through CREATION.co’s tracking updates. Each week CREATION.co’s tracking updates bring you the latest insights from the conversation of HCPs across the globe discussing Top 50 pharma, respiratory disease and more.

The Top 10 covid-19 vaccine candidates mentioned by HCPs on Twitter in February

February’s insights from HCPs mentioning covid-19 vaccine candidates on Twitter

February has seen another modest decrease in overall mentions of COVID-19 vaccine candidates, with HCP online discussion maintaining its focus on developments around Pfizer and AstraZeneca’s vaccines. News of Janssen’s vaccine receiving FDA approval late in the month was spread less intensively than earlier approvals, with more attention and shares directed towards data releases exploring efficacy against novel variants of coronavirus.

Whilst Janssen’s vaccine candidate has been subject to some second guessing due to unfavourable comparisons with Pfizer and AstraZeneca’s vaccine efficacy, reception of the approval has been met with enthusiasm by HCPs. With so many new approvals, some HCPs have attempted to summarise the data concisely for members of the public.

As with previous months, HCPs have directed their online discussion in many ways; some have attempted to dissect the data around all the newly approved vaccine candidates for the purpose of comparison amongst HCP peers. Others have directed their communication towards the public, where efforts have been made to downplay differences and emphasise the high efficacy exhibited by all approved vaccines.

HCPs also continue to inform and share news of logistical developments; one of the month’s most shared posts from Dr Eric Feigl-Ding celebrated the progress made on frozen storage of the Pfizer vaccine. In addition to celebrating the progress made by vaccine rollout efforts, many HCPs have continued to diligently dispel misinformation and encourage vaccination among members of the public in need of reassurance.

As the conversation develops and more obstacles towards a high uptake rate manifest themselves, let us continue to listen to HCPs’ analyses of the situation, as they are uniquely placed to provide insights that will be important for anyone wishing to contribute to protecting public health during this pandemic.

We will be tracking the online HCP conversation to identify trends and change in views relating to COVID-19 vaccines. You can stay up to date with HCP insights by subscribing to CREATION Knowledge e-journal.


  • Data for this research was analysed using CREATION Pinpoint® from the online Twitter conversations of HCPs around the world in English language (other languages are available), between February 1st – February 28th, 2021.
  • Vaccines tracked were the 178 COVID-19 vaccine candidates in clinical evaluation before 1 March 2021 (WHO Draft landscape of COVID-19 candidate vaccines).
