(Bloomberg) -- Latin America and the Caribbean, the region where the coronavirus outbreak caused the worst economic destruction and more than a quarter of the world’s deaths, is now falling victim to a slow inoculation campaign.Political fights and production bottlenecks are stymieing Brazil’s vaccination efforts. Mexico is struggling to source doses as its death toll surpasses India’s. Colombia only began administering shots last week.Such sluggishness alongside a recent spike in infections risks hampering an already slow-going economic recovery.“If vaccination and public health policy don’t succeed at reversing the trend that we’ve seen in recent months, clearly this recovery is at risk,” Alejandro Werner, the International Monetary Fund’s western hemisphere director, said earlier this month.Latin America’s economic rebound was already wobbling after a new round of lockdown measures in response to the surge in cases that began around the Christmas holidays. Since January, JPMorgan Chase & Co. trimmed its first quarter growth forecasts for Argentina, Brazil, Chile, Colombia and Mexico, citing concerns of a rising case load and new restrictions.The region contracted by more than 7% last year, according to the IMF -- the most in the world. The Fund doesn’t see output returning to pre-pandemic levels until 2023, and this year is off to rocky start.In December, Brazilian retail sales suffered their biggest drop for the month on record, pointing to a sharp slowdown in Latin America’s largest economy. Meanwhile, Mexico saw its recovery lose steam, as growth slowed to 3.1% from 12.1% over the last two quarters of 2020. And on Tuesday, Peru reported that its economy shrank 11.1% last year, the biggest contraction since 1989.Chile OutperformsActivity is expected to pick up later this year, but a strong rebound depends on vaccines becoming more widely available in the coming months. Underscoring the importance of an efficient vaccine rollout, investors are already rewarding Latin America’s only success story so far: Chile. The country is on pace to inoculate 75% of its population in just six months, according to Bloomberg’s Vaccine Tracker.This month, Moody’s Investors Service and Spain’s Banco Santander both revised upward their growth forecasts for Chile, setting it apart from its neighbors. Its economy will recover to pre-pandemic levels three to six months earlier than most other countries in the region, according to Nikhil Sanghani, an economist at Capital Economics in London.The Chilean peso has led gains among regional peers, rallying more than 3% so far this month.Read More: Chile Peso Joins Pound, Dollar on Vaccination Winners ListOther countries in the region are nowhere close. At the current rate, Brazil would take two-and-a-half years to reach the 75% level of inoculation, which is the threshold experts say is needed for a return to normality. In Mexico it is estimated to take 3.6 years to reach that level, and in Argentina, over a decade. The U.S., by contrast, is projected to reach herd immunity by the end of 2020.This outlook may improve over the next few weeks as some of the “teething problems” with the vaccine rollout start to ease, Sanghani said.Delays in deliveries have sent countries that relied heavily on particular vaccines, such as Mexico and Colombia, running to ink last-minute contracts with competitors. Argentina is trying to produce more shots locally.After dragging its feet for months in making vaccine orders, the administration of Brazilian President Jair Bolsonaro is running out of doses to sustain its vaccination campaign, leading nine state capitals including Rio de Janeiro to suspend immunizations.Self-InflictedThe hold-ups in the vaccination drive aren’t all self-inflicted.From the start, poorer countries have been pushed to the back of the line by wealthier ones that quickly sealed deals with drug makers, or are now commandeering vaccinations produced in their territory for their own citizens.Much of the Caribbean and Central America are still weeks away from kicking off their campaigns. Jamaica’s Prime Minister Andrew Holness last month accused rich countries of “hoarding” vaccines.Economists watching mobility trends are bracing for another hit to activity caused by people once again sheltering at home and businesses closing shop. Chile aside, they remain skeptical about restrictions relief for the rest of the region given their slow start and distance from major vaccine distributors.“Richer countries already started to buy out everything they could, only leaving bread crumbs for the rest,” said Joan Domene, a Mexico City-based economist for Oxford Economics Ltd.(Updates with Peru GDP contraction in seventh paragraph.)For more articles like this, please visit us at bloomberg.comSubscribe now to stay ahead with the most trusted business news source.©2021 Bloomberg L.P.
