Rome, 12 April (beraking latest news Salute) – “Social networks become the only channel to positively influence the overall reputation on anti-Covid vaccines“. On the contrary, online information sites, including digital versions of the main newspapers, have channeled negative opinions on vaccines to a greater extent, causing a marked decline in the reputation curve. “This is what emerges from a survey by Reputation Science, a company active in the analysis and management of reputation. Among the most evident results that emerge from the observation of about 215 thousand contents published between February and March, there is the new role played by social media in determining the reputation of vaccines among Italians. ” The analysis – underlines Auro Palomba, president of Reputation Science – tells us that something has changed and that social networks or users have adopted a more mature attitude than vaccines “.
“The online conversation in the last 2 months – explains Andrea Barchiesi, CEO of Reputation Science – has mainly focused on AstraZeneca, which alone collected 56.5% of the total conversations on vaccines. Pfizer / BioNTech (18.7%) and Moderna (9.8%) remain at a distance, while for other vaccines the volumetric curve has almost run out. Symptom of the pressure that the news regarding the AstraZeneca vaccine has exerted on the entire online conversation about vaccines, not just regarding the volumes, but also for the sentiment associated with it “.
The quantity and quality of the content related to this vaccine in the analysis period significantly influenced the trends in the reputation of the entire category, reports a note. Pfizer and Johnson & Johnson also recorded an increase in volumes, while for other vaccines such as ReiThera and CureVac, the data indicate a substantial decrease in volumes. Considering the vaccine category as a whole, the change in reputation over the period considered is negative. The distribution of opinions on vaccines, on the other hand, remains substantially unchanged, with 43% of the contents showing a positive attitude, 26% with a neutral position, and the remaining 30% a negative attitude; at the same time, positions are much more polarized than in the previous period, as shown by the significant increase in very negative contents, which went from 0.1% to 5.1%.
The opinions – continues the note – were mainly driven by issues relating to the administration of vaccines, which accounted for 21% of the total, followed by distribution; the polarization of negative opinions was instead influenced by the theme represented by the undesirable effects of vaccines which, although representing 13.2% of the total, were characterized by a significant number of very or extremely negative contents. The contents that have most moved the reputational levels in the negative area, also because they are characterized by high tones of criticality, are connected to the suspension, by Italy and other European countries, of the administration of AstraZeneca due to some suspected serious side effects. in people who had recently received the vaccine.
Among the events that have had the greatest impact on positivity, there are the approval of the J&J vaccine first in the United States, then in Europe and in Italy; the authorization of the administration of the AstraZeneca vaccine also for people up to 65 years of age; Moderna’s study to create an effective vaccine against the South African variant; the launch of the review of the Sputnik V and Curevac vaccines by Ema; the agreements made by Sanofi / Gsk for the production of the Janssen and Pfizer vaccine; the collaboration between Novartis and CureVac; the effectiveness of Pfizer / BioNTech demonstrated at 90%; the start of the administration to volunteers for the ReiThera experimentation.
Coming to the data on individual vaccines, the object of analysis that collected the most online content in the period under review is AstraZeneca, with 56.5% of the total. Followed by Pfizer / BioNTech (18.7%), Moderna (9.8%), Sputnik V (7.6%) and J&J (5.9%). From a qualitative point of view, the vaccine that achieved the best reputational impact between 9 February and 19 March 2021 is Pfizer / BioNTech (+539.07 r), followed on the podium by Sputnik V (378.87 r) and J&J (+338.75 r). The only vaccine to have a negative reputational impact is that of AstraZeneca, which in the survey period accumulated a negative value of -6137.83 r.
In light of the trends that emerged in the last two months, the distribution of sentiment among vaccines starting from December sees Moderna (+1850 r) in first place, followed by Sputnik V (+1027 r) and J&J (+470.7 r); in the last places we find Pfizer which, while catching up from the previous survey, remains in negative territory with -902 r, and AstraZeneca, in last place, with -6108 r.
