Now, to address the claim that this increase in vaccine hesitancy is due to "revisionism around the covid vaccines' spurious efficacy".
We know this is unlikely to be the case as the author of the study that hometruths is trying to claim shows this said:
This study suggests that paradoxically, despite the success of COVID-19 vaccination campaigns, vaccine confidence has significantly declined since the onset of the pandemic; the comparison of a pre- and post-pandemic cohort sheds light on the differential effect that the pandemic had on vaccine confidence in different demographic groups.
If the author is claiming that the vaccine campaigns were a success, then it's not reasonable to believe that "revisionism around the covid vaccines" is a likely explanation. Unless of course once again we are to be told that an anti-vaxxer knows the topic and data in the paper than the person who wrote it. Or we are to get vague hints that the author is somehow being influenced to make a false statement or change the conclusions in his study.
On the flip side, there's a bunch of actual evidence that shows the effect of vaccine misinformation on people's confidence in the vaccines and willingness to get them:
Abstract
Widespread acceptance of a vaccine for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) will be the next major step in fighting the coronavirus disease 2019 (COVID-19) pandemic, but achieving high uptake will be a challenge and may be impeded by online misinformation. To inform successful vaccination campaigns, we conducted a randomized controlled trial in the UK and the USA to quantify how exposure to online misinformation around COVID-19 vaccines affects intent to vaccinate to protect oneself or others. Here we show that in both countries—as of September 2020—fewer people would ‘definitely’ take a vaccine than is likely required for herd immunity, and that, relative to factual information, recent misinformation induced a decline in intent of 6.2 percentage points (95th percentile interval 3.9 to 8.5) in the UK and 6.4 percentage points (95th percentile interval 4.0 to 8.8) in the USA among those who stated that they would definitely accept a vaccine. We also find that some sociodemographic groups are differentially impacted by exposure to misinformation. Finally, we show that scientific-sounding misinformation is more strongly associated with declines in vaccination intent.

Findings
High levels of misinformation exposure were observed among participants, with 73% reporting some exposure to misinformation about COVID-19 vaccines in the past 6 months. Exposure to misinformation was directly correlated with vaccine hesitancy. Among those who did not report any exposure to misinformation, 73.8% of respondents were vaccinated. That number fell to 62.9% with exposure to just one misinformation theme and 52.2% for six or more (χ2 = 11.349; φ = 0.138; p ≤ 0.05). Politicization was also found to be a major factor in vaccine hesitancy, with 73.4% of self-identified Democrats being vaccinated, compared to only 58.5% of Republicans and 56.5% of Independents (χ2 = 16.334; φ = 0.165; p ≤ 0.001). Both misinformation exposure and political affiliation were strong predictors of vaccination even after accounting for other demographic predictors.
Results
Looking across U.S. states, we observe a negative association between vaccination uptake rates and online misinformation (Pearson R = –0.49, p < 0.001). Investigating covariates known to be associated with vaccine uptake or hesitancy, we find that an increase in the mean amount of online misinformation is significantly associated with a decrease in daily vaccination rates per million
This study in particular points out some examples of sources of vaccine misinformation:
A lot of which we've seen on this thread at one point or another.
