Answer: No

This is a plot of my resting heart rate (as measured by Apple Watch). The x-axis is the number of days before and after each shot.

Code in R

```covid_shots <- readr::read_csv(“data/COVID Shots.csv”, col_types = cols( Day = col_double(), Date = col_date(), RHR = col_double(), Shot = col_character() ))

covid_shots %>% select(Day, RHR, Shot) %>% 
  ggplot(aes(x=Day-3,y=RHR, color = Shot)) +
  geom_line() + geom_point() + 
  ggthemes::theme_fivethirtyeight() + 
  geom_vline(xintercept = 0, size = 2, color = "black") + 
  labs(title = "Does the Pfizer Vaccine Affect My Resting Heart Rate?",
       x = "Days Before/After",
       y = "Resting Heart Rate"
  )

```
